Hygrogen and oxygen from water

[TheNikolaishapland]

This could be a new great energy source if they find a way to get more energy out than in

[fattongan101]

hold up, so you can make oxygen with this stuff?

[lyrison]

I have an electrolys setup like this using H2SO4 as an electrolyte. The only issue is the cell produces more than 10 times the amount of H2 as O2. Why? I'm using carbon electrodes, btw. where does the O2 go.

[sparsh304]

well done...:)



[syprix]

what happens to the salt? where does it go?

[Cryoglific]

@syprix He/she used sulfuric acid, but I don't know where that goes.

[emmettebrown]

what if I used a.c. instead of d.c. ?



[helsangels2]

@emmettebrown this would actually mean that the gases would basically mix, as the annode and cathode would keep swapping round...

[viruz7776]

learnt more from this video than in highschool

[bro589]

what i'm interested in is what substance was used at the anode and the cathode of the apparatus to pass current into the water. Since the process of electrolysis is extremely corrosive to a metal, even that stainless steel emits rust, what substance was used that didn't rust in the process.

[Madc0w95]

@bro589 I Do not know what this particular person used for them, but you could use graphite because it is a conductive non-metal, and thus it will not corrode nor rust.

[startrekwarsmixguy]

@bro589 Most likley it was Platinum, since it is very unreactive, at least, thats what we used.

[bro589]

@startrekwarsmixguy Platinum is perfect, except for its price. I'm thinking non metals but haven't tested anything. What did you do electrolysis for?

[startrekwarsmixguy]

@bro589 Chemistry Project, anyway, if your looking for non metals, you are best off with carbon, although it does not conduct electricity as well as platinum, it's a lot cheaper, you could just use the 'lead' out of a pencil, and it doesn't corrode...

[bro589]

@startrekwarsmixguy thats what i was thinking, would probably want something thicker than a pencil lead, for lover resistance. But i had some concerns that carbon might bind with ether H or O, and CO is not something i want to be around.

[startrekwarsmixguy]

@bro589 No, CO isn't really the best thing to be around, but since Oxygen is Diatomic, your most likley to get CO2, if anything at all, which is unlikley due to the presence of water. But just to be on the safe side, make sure each tube is sealed at the top, to stop any nasty gasses getting out.

[abobjenkins]

what is the name of the glass tube thing?

[bro589]

@abobjenkins its a hoffman apparatus

[abobjenkins]

@bro589 thanks, but i already heard the name in another video :-)

[evange123]

why distilled water??

[xplodestudio]

@evange123 The water turns into the two gasses that make it, they cant carry what ever is in the water with it, so you get a build up and it gets clogged.

[endimion17]

It's a shame that when yousearch for electrolysis, you mainly get clips from crackpots that claim it can be used to extract energy from water.

Face it, electrolysis requires more energy than you can obtain by recombining produced gasses back to water. Thermodynamics is being taught in high schools and colleges. Theory and experiments. That's how the world works. No perpetuum mobile bullshit.

And this "HHO" shit, jeez, that's like a New Age buzzword for a "mixture of hydrogen and oxygen" or what?

[25thedarkside]

how do I measure the amout of gas created??

[pepperpie88]

by far the clearest video on this topic

[baseball1949]

why is there more hydrogen, is it cause there's 2 h's in water?

[vesper2136segway]

@Dem0d1ck Actually, Hydrogen gas is H2 and oxygen gas O2, meaning that there are as many hydrogen atoms as there were water, and half as many oxygen. H2O is not being separated into H H and O, it is being separated into H2 and then 2 oxygen atoms combine into O2

[nealshireman]

@vesper2136segway do the O2 molecules have double bonds?

[vesper2136segway]

@nealshireman Yes there are covalent bonds in oxygen molecules

[nealshireman]

@vesper2136segway just learned about the types of bonds in September in 8th grade ;)

[alexin2012]

Hi, I would like to post this video on ASM's City of Materials website to help illustrate electrolysis. Who can I contact to gain permission to use this video?

[elgrau1]

did they just take apart water? hahaha

[ihateliamshow]

what is the name of the device shown in the first 4 seconds of the video?

[Dem0D1ck]

You don't need to test with a glowing stick. Since water, H20, is 2 hydrogen atoms and 1 oxygen atom, it stands to reason that twice as much hydrogen would be produced than oxygen when electrolysing.

Still, an interesting video.

[TheMattCosta]

wir haben erst letzte chemiestunde mit dem hofmanscher wasserzersetzungsapparat gearbeitet

[pp9pp7oo9]

Can someone tell me the materials that are in this video, PLZ!?!?!?!

[sbstransitbuses]

@pp9pp7oo9 Um water?

[polos505]

I just heated a potassium chlorate to produce Oxygen, I'll try this method next time. Thanks for sharing.

[jupjupz]

Wouldnt have been funnier if he mixed up the tubs :P

[nealshireman]

@jupjupz (I'm not sure if this is what you meant) it would be even funnier if he mixed the glasses, then ignited them. BANG! no more test tubes

[jupjupz]

@nealshireman Just ment.. he opened the tube and stuck his hand in with the match, would have burnt his hand :P

[RomanGeneral90]

Good vid!

How can I make electricity from HHO. To power a light bulb or somthing that requires eletricity?

Plz help? Have searched and can't find anything.

[sovereignenergy]

you do reverse water electrolysis. look up Proton exchange membrane fuel cell on wiki

[KnightFromSpace]

@sovereignenergy o_o"

[boxsaspen]

@RomanGeneral90

U could use a fuel cell

[kiliev2007]

Very nice demonstration!

[chucksheen]

Awesome!
