Electrolysis of water

[yshemtov7719994]

into sodium and chlor..



[legoboy1234567890]

what about chlorine and sodium if its salt water

[elementcollector1]

@legoboy1234567890 The anode forms chlorine gas, which is highly soluble in water, oxygen gas, which is not. The cathode forms hydrogen gas and sodium hydroxide.

H2O+ NaCl ->(e-) NaOH + H2 + Cl2

@bingyancai88 Actually, it depends on the concentrations of the ions in solution if oxygen gets oxidized. The Estandard voltage for the oxidation of oxygen: 2H2O(l)---> O2(g) + 4H+ + 4e- is -(1.23V), and is very close to the Estandard voltage of chloride ion oxidation voltage of -(1.36V): 2Cl- ---> Cl2(g). So, depending on on how conentrated the chloride ions are, you will either get chlorine gas, or oxygen gas. That is why it is important to know your stoichiometry levels BEFORE you do this.

[linuxpowerification]

what salt you used??? sodium chloride?

[pyrotec101]

@linuxpowerification  Duh O_O

[linuxpowerification]

@pyrotec101

Duh what??? it could be other salt that would not release chlorine.

[pyrotec101]

@linuxpowerification it will always produce chlorine gas... This electrolysis will also produce sodium chlorate.... if you run it long enough and then filter and boil the water off... you are left with 65% + pure sodium chlorat used in fireworks and rockets ^___^ check some of my videos

[linuxpowerification]

@pyrotec101

you mean sodium chlorat or sodium hydroxide? :)

[pyrotec101]

@linuxpowerification yea more often you end up with sodium hydroxide witch isnt used in pyrotechnics -___- i need a new charger because im not getting enough power.... and i also need to make air tight seals so my wires and anode/cathodes wont sizzle from all of the evaporation.... iv actually started a fire use an 1 amp ac dc charger and hydrogen gas..... i need thicker wires lol

[sliderulex]

@linuxpowerification Yes, you could use Sodium Bicarbonate for instance. That would not release chlorine gas, just carbon dioxide gas. A low concentration of Sodium Bicarbonate dissolved in the cup is all you would need to create your hydrogen and oxygen gases from this electrolysis.

[miodje678]

it is bad video !!!!

[psychowaffle2010]

u said that it is split into hydrogen and oxygen, well its true, but i have a fealing that u used salt, if u did it would split into hydrogen and chlorine

[Guiitaristt]

@psychowaffle2010 depends on how much salt he used and what the voltage was.

[PersianElite95]

@psychowaffle2010 you've right!

[owenhitman294]

..which is the function of the two pencils?... You're not gonna find carbon in pure form using house-hold items anywhere else i don't think.

btw the salt is used as an electrolyte to host the connection: since water isn't a great conductor of electricity.

Since it takes about 2V to split oxygen from the hydrogen: i don't know whether splitting chlorine from sodium would require more current? So using 3V battery might be ideal. Slow but ideal if you just want O2. H2 is produced on the other end.

[nealshireman]

@owenhitman294 you can find carbon in a diamond ring, but you're gunna have a herd time comducting electricity with it =D

[g25a25c]

@nealshireman not really, if its blue diamond it will conduct very will better then copper!

[nealshireman]

@g25a25c but it isn't pure carbon, it has boron mixed with it =D

[aCagedApe]

The book I read about this in told me to use carbon electrodes.

[nicholasgonzalez]

@Henrik4950 salt is sodium chloride? =o

[geekofsteal]

@nicholasgonzalez yes

[geekofsteal]

@Henrik4950 do you mean sodium chloride? "ate" implies oxygen in the formula. Do you mean this?

[winster626]

what is the material of the electrolytes?

[Xerodim]

i think Carbons c-c-c-c-c-c-c,... not sure though.

[xxEximiousxx]

Uh.... it produces no oxygen O2. It produces hydrogen and chlorine gas CI. How ever chlorine gas isn't as poisones as you think. Swimming for an hour will give you MUCH MUCH MUCH more exposure than sitting next to brine being electroylsised. it gives of miniscule amounts. Not to mention its heavier than air. so if your standing up, ur fine. it is heavier than water, so collect it by placing something over the negative terminal. itll turn brownish and stain.

[1natan]

if salt is used( sodium chloride) then chlorine is produced.....if sodium hydroxide is used o2 is produced

[geekofsteal]

@1natan Really?? AWESOME!! (not sarcastic) If that's true, then I've just made a personal discovery. :P

[Mrluisao17]

@xxEximiousxx

actually it produces hydrogen oxygen and chlorine

[enadon1]

mix with salt and het sodium hydroxide (flammable), chlorine (poisoness), and sodium chlorate (oxidizer).

[Cyberlord358]

NaOH isn't flammable!

[MagicMussh]

lol the only flammable substance their is hydrogen gas....

[picaticatara]

Fill up a ballon and then detonate it under your enemie's bed.

[TrentHalls]

I've been doing a similar project and I was wondering if the size of the electrodes effects the ratio of hydrogen vs oxygen produced.. for instance if you had a + electrode twice as big as the - would you produce equal amounts or even more oxygen than hydrogen?

[nitrogeb]

burn the idrogen

[yokosubagyo]

it's cool

[richonyou]

Hi! could you please tell me what kind of pens are you using? what is exactly salt-water? what are the proportions? Thanks for answering. Regards from Sweden!! Richard Appelgren

[mathfreak123]

Regular pencils can be used because the "lead" is graphite, which conducts electricity. Salt water could be any type of solution of water. Some salts that can be found in the house are sodium chloride (table salt), and sodium bicarbonate (baking soda).
