the reaction is not exactly correct, you need to remember that using NaCl instead of the most comom H2SO4 you will have a different soluction, in fact you would produce no O2, but Cl2 (That tends to combine on anode more than O2), but it was nice!
actually hydrolysis is any reaction that creats hydroxyl ions. this reaction is electrolysis but more specifically water electrolysis. The splitting of molecular bonds using electricity. Great job mhafter!
@jsmithmilitary Really? how so? ok for thos who are idiots please at least google hydrolysis! before you mAKE A FOOL OF YOUR SELF.. OR THUMBS DOWN ME HAHAHA
Hmm, quite a good "how to" video. And most of what you said was okay except for the fact the Anode is marked as - and the cathode as + , its the otherway around.
Should have done oxidation and reduction. Also, the anode and cathode thing changes between chemistry and physics sometimes (my electromagnetism course last semester got a bunch of us confused because of it)
Dude! Elecrolysis of salt (sodium chloride) doesn't make hydrogen it makes Sodium and Chlorine, the reason one electrode doesn't do anything is cos it is only making sodium and it isn't a gas so it just stays around the electrode. This is for the last comment by the way not the video.
Electrolysis of molten sodium chloride will make sodium and chlorine but it needs to be melted at 801 degrees celsius, the average home chemist will not have these means though.
i did this with salt(i now know it makes chlorine gas) and i could only get hydrogen but there were no bubbles coming off the other wire. HELPPPP!!!!!!!!!!!!!
the undissolved salt would not be a precipitate............just undissolved salt.........a precipitate forms when an insoluble product is made in a displacement reaction between soluble chemicals.
Don't use NaCl, it releases chlorine gas. Never put your hand over the bottle. Use a stopper of some kind, and less gas will escape. This will also protect your hand from any accidents!
Salt is not a good solvent for conduction because an amount of clorine will be released in additon to the hydrogen and oxygen. vinegar or lye would probably be better.
Mark? Sure it isn't Marx with that "doo"??? As in Graucho Marx? Just kidding. Anyway you do get chlorine gas (poisonous and corrosive gas) but probably not enough to hurt you with the little test you did. The little bit of H, H and O you get in that is not that dangerous in an unrestrained plastic container.
Hi, i just wanted to share that increasing the temperature of water will hardly increase the solubility of sodium chloride. Hence, it is not necessary to heat up water in your demo. :)
dude you can do it and no danger is involved. ok you electrolysed water but also did the test for hydrogen used in laboratories. nothing dangerous. just a simple "pop test". and the negative electrode is the cathode whilst the positive is the anode. despite that nice going good experiment and good electrolysis of water.
no, you would need to separate both electrodes with a membrane and use platinum electrodes, then the product will be chlorine and sodium hydroxide dissolved in the water.
wow that was great, just a tip if you add too much salt i have heard that the electrolysis can produce Sodium Chloride, a very toxic gas. if the water turns green then you should throw it out. it would be safer to do it in a ventilated area. but then again i havent gotten it to work, do the cathode and anode need to be anything specific or can it just be wire
Sodium Chloride is actually the chemical name for table salt :D.
The thing you're thinking of might be Sodium Hypochlorite [NaOCl]...which is bleach. That IS bad. I did that by accident once and had to pour throw away the bowl, there was a rim of green stuff on the side...probably copper chloride from my copper terminals :D
ye its the chlorine gas you wanna watch out for! and use graphite for the electrodes as they dont corrode, you can get it from a pencil or inside a non alkaline battery
woah woah woah...i thought the cathode was the negative electrode and the anode was the positive. the cathode attracts negative ions and the anode attracts positive ions.
BTW: Mhafter this experiement was really cool! I tried it out, but on a lower scale. My power source was a D battery. I couldn't have it any more powerful, my teacher told me. But it still makes a great science project and this video was great. It helped me understand the concept of electrolysis even better. Thanks for a great video.
if you put NaCl in the water it will result H2 and Cl2 as gases! if metal rods contain Fe or Cu
in the electrolite will result green Fe(OH)2 or Cu(OH)2. Fe(OH)2 will be oxidated by air to brown-yellow Fe(OH)3. electrolysis of NaCl solution is a way to obtain NaOH
you will have to electrolyse it at a high temperature to not let the chlorine dissolve in the water, thus creating HOCl (wich is then instantly reacted with NaOH to NaOCl,NaClO2,NaClO3,NaCl04 respectively hypochlorite (bleach, chlorite,chlorate,perchlorate)
anyway, this isn't the best way to produce NaOH, a better way is reacting CaO, Na2CO3, water....
without any attempt to dis encourage you my friend your whole process of making H2 is lame you used 7 Amps of power to make too little H2. Now i just now this by the explosion you made and it just isn't beneficial. Now i have thoughts that u made this because you didn't want to produce too much H2 so the bottle wouldn't go off.. My advice? Just play around with the electrolyte and don't put in that much... or use electrodes of much more surface than 2 electrodes made of wire.
You're absolutely right. I am very familiar with the principles that would increase the hydrogen production of this model, but this was simply a proof-of-concept, not something designed to serve an industrial purpose. What you might not have observed, however, was the volume of the explosion - the camera doesn't do it justice. Any bigger and that horrid whistle of the gas combusting in a small bottle neck will most likely destroy my hearing!
True cameras have auto volume leveling control... But apart from this you can look into the bottle when bubbling and see the magnitude of this reaction.
I am not using a battery but instead a power supply. It transforms standard wall current into DC current. You can probably find one in an electronics or hobby catalog.
Actually, I'd like to know where you got that idea... Salt... Chlorine? It's simply a catalyst to charge the water, to shift the electrons in the h2o, in order to make hho. Chlorine gas as you're thinking of it would be formed when you mix ammonia with bleach. Not salt with water and electricity.
yes... it is very true that it is a catalyst. but in order to be a catalyst, the process requires the salt to loose a few electrons every so often. this creates more hydrogen because once the NaCl is split, the chlorine is released and the pure sodium reacts with the water releasing more hydrogen.
yes, the chlorine can be formed, the sodium has a higher reduction potential, so it cannot be obtained this easy way. THE ION Cl- CAN TAKE AN ELECTRON FROM THE CURRENT TO FORM Cl2!
i'm stupid, the Cl- ion loses an electron in the anode, and forms Cl2, it doesn't gets alive out of the water, since it reacts with it to form ClO- (Hipochlorite).
I made this experiment and I got a yellow solution at the end that had a smell like the comercial chlorim used as a cleanig product.
No, it needs the match to do that. It simply "starts" the reaction, in which energy is released to form the water again (the energy came from the battery in the first place).
If the gasses mix, they don't turn back into water, all it does is mix the gasses together, to make it water again you need to light it, then you get steam. Idiot.
hello i have a question i tried the same thing except lighting it and wen i put the two wires (charged) into the water only hydrogen is coming out not oxygen plz respond i have a project due tommorow!
Cool hair!!! I have 2 hydrogen generators installed in my car and have noticed a huge drop in production lately, with temps in the 20s and amperage draw less than 1 amp...Maybee more electrolyte is needed? Thanks for the informational Vid!
I did this for my 5th grade science fair, lol. Dangerous- Yes. but on a small scale, no. I found the best electrolyte is sulfuric acid. To get the acid, just go to your local autopart store and buy it.
Oh, also, isnt chlorine (poisonous) produced when you do this? I did an electrolysis experiment with salt and I have a feeling it produced a bunch of chlorine. Better be more careful next time...
Thanks ajd, but you are about the 100th person to mention this. Believe me, I will be much careful next time (unfortunately I haven't had the opportunity to do this again, but I'm sure I will sometime). A safer choice is baking soda, or any other salt (chemically speaking) with a non-harmful cation.
experiments almost always develop hangups in mid-stroke. meanwhile, I hated seeing that match hover more-or-less over the matchbox. Fastidiously separating things can be an important safety tool. Like striking the match, putting the box where you won't be going again till after alldone, then approaching the bottle. It's a thinking paradigm.
idea why it whistles: H2 near neck suddenly burns with some air at top. hot expanded gas pulses outwards, echoes inwards, new air meets H2, burns fast again. Combustion delayed by mixing time pumps the resonance of gas in the bottle (same pitch as blowing over mouth of bottle) and resonance enchances mixing rate so combustion is faster. Not sure, just an idea...
I mean , i'm not going to duplicate this video but i was doing this science fair project with electric currents and the growth of plants and the biggest battery i could find was a 6 volt, 4 A/H. (i didn't want to take my car battery out)
Oh and by the way, plants die if you introduce their soil to an electric current ;)
cool video, we made our first cell & did a vid too. Keep up the good work - I also liked the science lesson.
BTW if the cathode reaction produces more hydrogen, then wouldnt it be better to more positive plates than negative ones? I'm not smart on this stuff, but perhaps you can help out.
If it says "don't do this at home," then don't do it at home. I know some people might ignore that, but that's their prerogative. The mature course of action would be to preserve the original movie; there are people in this world who do far more stupid things on their own, without an "instruction video." (which this NOT meant to serve as!)
Sorry, but no. The ignition of H2 gas is my favorite part of the video, and most likely the favorite part of many other people. I will not censor my video in an effort to cater to those to stupid to heed my warnings. ---next comment...
Thats not even equivalent to a fire cracker.You have bigger things to worry about like Leaders behaving like Dicktators. Do us a favor and don't become a politician and don't vote.Leave that to the smart people. kid the only thing you should leave out of the video is(don't try this at home)it has tendencies to scar people.
be careful with that... i ignited about 1 litre in a bottle with only a small hole (6-8mm), and the damn thing blew up really hard... and getting hit by the kork wasnt very pleasant either...
That's pretty good. Someday he's going to drasticlly improve the explosion and his Mom's going to be really pissed when she comes home to find her kitchen blown up, but that would be a good thing because he discovered the utimate hydrogen producing gismo.
Yeah, I think the noise is the fast passage of air through the small neck of the bottle. As for the power parameters, I don't think there is any necessary power requirement, as long as it is pretty big. So don't use any little AA batteries (save those for electroplating) and try to get something that will give you at least 12v with around 2 amps for significant hydrogen production. Again, it all depends on the setup. Anyone else have thoughts on this?
hello mark. ty 4 this video. i would just like to ask, is it possible to put the wires in separate bottles to collect ONLY hydrogen in a balloon? i dont want to collect the oxygen and hydrogen together because i dont want any exploding stuff, just some hydrogen to lift balloons. also, will there b enough h2 generated to fill the balloon if possible?
Interesting point... I guess it is theoretically possible: the Cl- ions bonding with the H+ ions before they have a chance to be used in another reaction. However, then they would just dissociate again and we would be back where we started. Anyone else know better than I do? Anyway, with salt the thing to be worried about is Cl2 gas, not HCl.
To continue the last comment, it is really confusing, but I got the equations directly out of the book, so I am pretty sure they are right. Still, it was a while ago and I forget easily. Thanks again for all your praise on my video.
Thanks guys, I really appreciate it. I haven't seen any really good comments on here in a while (I deleted some of the really bad ones.) Anyway, I think I got it right with the anode and cathode thing, though. The anode is where electrons flow out of, and in this case, a power supply is pushing electrons out of the negative side, and splitting the H2O as described in the "science segment."
The video was almost perfect! (You did confuse anode and cathode, though. A cathode is negative, and an anode is positive.) This is the best vid on electrolysis I've seen.
I applaud you Mark (I hope that is your name right?)
It was very well explained and I am glad that you are formal about the names of the elements. And that guy wargod, and all the others you Dis you, they need to do some more research.
I can envision some type of 12v system where a car battery is used for the electrolysis source. The emitted hydrogen gas could be contained in something for later use? A car alternator could be modified to be operated via wind or solar power to supply a constant charge to either the battery, or utilize the electromechanical output of the alternator directly. Interesting stuff. Why are we still using fossil fuels?
If you did that, you would have a balloon full of Hydrogen gas! That would be very cool. I believe there are some videos of that in the related video section.
OK, I couldn't understand half of what you just said... but CO2 (carbon dioxide) is only harmful in very high quantities in enclosed environments. In fact, CO2 is what humans and other animals breathe out. The only way the production of CO2 could be remotely dangerous is if you do it inside some sort of plastic bubble.
OK. guys? Thanks for all you comments, and I really appreciate them. But if I see one more comment about how I am making Cl2 gas, I am going to be seriously mad. Everyone, including me knows this now; read the first comments. The next person who posts a Cl comment will get it deleted, OK?
im not sure if you realize the iorony in your statement but for yourself and others i would like to point out that salt NaCl is sodium and chlorine. you force these to seperate during electrolosis so this process can indeed be dangerous
The chlorine wouldnt be produced cos you need an extremely high concentration of sodium chloride for the chloride ions to be discharged, as OH- ions are much more easily discharged than Cl- ions
I did it before I saw this video. I used aproximatly 62v dc,4 amps. I used water and salt but the water was cold. For the electrodes, I used some alagator clips. I left it siting producing h2 for about 10 min. When I came back the water was a green and brown color, some blue, and after checking amps it was just under 15 amps. after pulling out the aligator clips, I noticed that about half of the positive clip was gone. The water and what ever mixed in was very hot. What did I make?
It seems as if you made a lot of things. Assuming the alligator clips were steel, you made aqeous (dissolved in water) FeC3 (steel), H2 released into the atmosphere, maybe some O2 released, and some Na+ dissolved and Cl released. Trying to tell you exactly what was in there and how it happened is hard, and my chemistry knowledge is still growing. Whatever it was, I wouldn't drink it or smell it if I were you.
Not quite. Since the Hydrogen is dissolved as a polyatomic ion, the chlorine will turn into a gas, and while some gas can dissolve in water (like in pools), the solution will quickly saturate and the chlorine will enter the atmosphere.
I hear sodium sulfate is a good electrolyte, since the Cl- from NaCl can be oxidized at the anode, creating noxious Cl2. By the way, H+ is not polyatomic.
Thanks. Did I say something about H+ being polyatomic? Probably. At the time I was thinking about OH- and stuff. I'm probably wrong, but we haven't gotten that far in chemistry yet. :) Thanks for your comments.
dam. we did this in chemistry. i cant remember the exact stuf but it blew up. i mean glass everywer. teacher bleeding. i couldnt hear for a few minutes. i cant find a video that that happened on. im nearly sure im lookin for the right thing. can anyone help me if im not
You can drastically improve your electrolyser's efficiency by powering it with a pulse rather than a constant current. This is because you use up energy pulling electrons through the water heating it up. It's not the flow of electrons through the water that causes the water molecule to split, it's the electro magnetic force! Pulsing the current restricts electron flow reducing energy consumption through heat dissipation.
Interesting... I would definately give it a try if I had some sort of AC generator; and I am not hooking it up to the mains. I'll see what I can do in my spare time.
haha, wow, you explain it better than my science teacher :D. you totally made me understand electroysis of water and now i might pass my test tomorrow! thanks so much. you should do more of these videos. frigin awesome.
Might be the chlorine or just the fact that hydrogen is lighter and is floating out of your bottle first. But the flame looks like a hydrogen flame, not hydrogen-oxygen. If you electrolyse filtered water, without salt, the gas explodes with a big bang!
Trust me, if you explode 2H2 + O2 you will need to wear ear muffs. Exploding half a litre will smash windows. Be extremely careful with this gas. Do not use matches, use a BBQ lighter, and don't do it inside.
idid this at home... ohhhhh sooo scary >.<... it didnt work as planed for me though the water formed some weird green and orange gunk and bubles...

Oh, also, isnt chlorine (poisonous) produced when you do this? I did an electrolysis experiment with salt and I have a feeling it produced a bunch of chlorine. Better be more careful next time...

Thanks ajd, but you are about the 100th person to mention this. Believe me, I will be much careful next time (unfortunately I haven't had the opportunity to do this again, but I'm sure I will sometime). A safer choice is baking soda, or any other salt (chemically speaking) with a non-harmful cation.

experiments almost always develop hangups in mid-stroke. meanwhile, I hated seeing that match hover more-or-less over the matchbox. Fastidiously separating things can be an important safety tool. Like striking the match, putting the box where you won't be going again till after alldone, then approaching the bottle. It's a thinking paradigm.
prfesser56 4 years ago
idea why it whistles: H2 near neck suddenly burns with some air at top. hot expanded gas pulses outwards, echoes inwards, new air meets H2, burns fast again. Combustion delayed by mixing time pumps the resonance of gas in the bottle (same pitch as blowing over mouth of bottle) and resonance enchances mixing rate so combustion is faster. Not sure, just an idea...

where did you get the 12 volt battry?
I mean , i'm not going to duplicate this video but i was doing this science fair project with electric currents and the growth of plants and the biggest battery i could find was a 6 volt, 4 A/H. (i didn't want to take my car battery out)
Oh and by the way, plants die if you introduce their soil to an electric current ;)

cool video, we made our first cell & did a vid too. Keep up the good work - I also liked the science lesson.
BTW if the cathode reaction produces more hydrogen, then wouldnt it be better to more positive plates than negative ones? I'm not smart on this stuff, but perhaps you can help out.
Good stuff.

If it says "don't do this at home," then don't do it at home. I know some people might ignore that, but that's their prerogative. The mature course of action would be to preserve the original movie; there are people in this world who do far more stupid things on their own, without an "instruction video." (which this NOT meant to serve as!)

lol funny noise. is there a necesarry voltage/amperage/wattage for optimum hydrogen and oxygen production?
musclecar383 4 years ago
Yeah, I think the noise is the fast passage of air through the small neck of the bottle. As for the power parameters, I don't think there is any necessary power requirement, as long as it is pretty big. So don't use any little AA batteries (save those for electroplating) and try to get something that will give you at least 12v with around 2 amps for significant hydrogen production. Again, it all depends on the setup. Anyone else have thoughts on this?

you may want to use baking soda instead of salt for the ions, because I've heard something about hydrochloric acid when you use salt
squirrelgecko 4 years ago
Interesting point... I guess it is theoretically possible: the Cl- ions bonding with the H+ ions before they have a chance to be used in another reaction. However, then they would just dissociate again and we would be back where we started. Anyone else know better than I do? Anyway, with salt the thing to be worried about is Cl2 gas, not HCl.
Thanks for your comment,

Thanks guys, I really appreciate it. I haven't seen any really good comments on here in a while (I deleted some of the really bad ones.) Anyway, I think I got it right with the anode and cathode thing, though. The anode is where electrons flow out of, and in this case, a power supply is pushing electrons out of the negative side, and splitting the H2O as described in the "science segment."
mhafter 4 years ago
The video was almost perfect! (You did confuse anode and cathode, though. A cathode is negative, and an anode is positive.) This is the best vid on electrolysis I've seen.

I can envision some type of 12v system where a car battery is used for the electrolysis source. The emitted hydrogen gas could be contained in something for later use? A car alternator could be modified to be operated via wind or solar power to supply a constant charge to either the battery, or utilize the electromechanical output of the alternator directly. Interesting stuff. Why are we still using fossil fuels?

OK, I couldn't understand half of what you just said... but CO2 (carbon dioxide) is only harmful in very high quantities in enclosed environments.

The chlorine wouldnt be produced cos you need an extremely high concentration of sodium chloride for the chloride ions to be discharged, as OH- ions are much more easily discharged than Cl- ions

I did it before I saw this video. I used aproximatly 62v dc,4 amps. I used water and salt but the water was cold. For the electrodes, I used some alagator clips. I left it siting producing h2 for about 10 min. When I came back the water was a green and brown color, some blue, and after checking amps it was just under 15 amps. after pulling out the aligator clips, I noticed that about half of the positive clip was gone. The water and what ever mixed in was very hot. What did I make?
prometheus53189 4 years ago
The scumy substance could be Iron carbonate because it was done in hard water, as this is probably less soluble than calcium carbonate.
prometheus53189 4 years ago
It seems as if you made a lot of things. Assuming the alligator clips were steel, you made aqeous (dissolved in water) FeC3 (steel), H2 released into the atmosphere, maybe some O2 released, and some Na+ dissolved and Cl released. Trying to tell you exactly what was in there and how it happened is hard, and my chemistry knowledge is still growing. Whatever it was, I wouldn't drink it or smell it if I were you.

wont the salt turn to chlorine gas and disolve back to water turning it into acid because of the hydrogen
alisanchez74 4 years ago
Not quite. Since the Hydrogen is dissolved as a polyatomic ion, the chlorine will turn into a gas, and while some gas can dissolve in water (like in pools), the solution will quickly saturate and the chlorine will enter the atmosphere.

theinsolentfish 5 years ago
You can drastically improve your electrolyser's efficiency by powering it with a pulse rather than a constant current. This is because you use up energy pulling electrons through the water heating it up. It's not the flow of electrons through the water that causes the water molecule to split, it's the electro magnetic force! Pulsing the current restricts electron flow reducing energy consumption through heat dissipation.

Might be the chlorine or just the fact that hydrogen is lighter and is floating out of your bottle first. But the flame looks like a hydrogen flame, not hydrogen-oxygen. If you electrolyse filtered water, without salt, the gas explodes with a big bang!
Trust me, if you explode 2H2 + O2 you will need to wear ear muffs. Exploding half a litre will smash windows. Be extremely careful with this gas. Do not use matches, use a BBQ lighter, and don't do it inside.
