neo007 Posted March 20, 2004 Share Posted March 20, 2004 I know this is basic stuff, but does the electrolysis of water produce oxygen and hydrogen, or hydrogen and OH-. Or are they the same thing? Link to comment Share on other sites More sharing options...
YT2095 Posted March 20, 2004 Share Posted March 20, 2004 it produces 2 parts Hydrogen and 1 part Oxygen Link to comment Share on other sites More sharing options...
neo007 Posted March 20, 2004 Author Share Posted March 20, 2004 YT2095 said in post # :it produces 2 parts Hydrogen and 1 part Oxygen so therefore it would produce oxygen and hydrogen gas right? Link to comment Share on other sites More sharing options...

TheBigDino Posted August 19, 2004 Share Posted August 19, 2004 can anyone explain why the water turns yellow after electroylsis?? Link to comment Share on other sites More sharing options...
Lance Posted August 19, 2004 Share Posted August 19, 2004 You would have to specify what you used for electrodes and what you used to make the water conductive. Link to comment Share on other sites More sharing options...
TheBigDino Posted August 19, 2004 Share Posted August 19, 2004 I used two paper clips and nothing as the water condcutor. Link to comment Share on other sites More sharing options...
swansont Posted August 19, 2004 Share Posted August 19, 2004 can anyone explain why the water turns yellow after electroylsis?? If there was any sulfuric acid in the water it would tend to turn yellow when the acid decomposed. Link to comment Share on other sites More sharing options...
brokenbin Posted August 19, 2004 Share Posted August 19, 2004 well, you probably used sodium chloride as electrolyde to made water a conductor. So, when you electrolyse the water, sodium ions comes together with the two electrolites, paper clips for example. The actual substance which turns the water yellow is cloride ions.

raivo Posted August 20, 2004 Share Posted August 20, 2004 Yellow color is probably due of iron or nickel ions that go into solution from those paper clips. In fact you can completely dissolve your anode this way. Link to comment Share on other sites More sharing options...

TheBigDino Posted August 24, 2004 Share Posted August 24, 2004 does anyone know why the water turn green when i do electrolysis with sodium chloride solution? is it chlorine? by the way whats produced when i do electrolysis to sodium chloride solution? i know one is hydrogen gas, but whats the other?

swansont Posted August 24, 2004 Share Posted August 24, 2004 The word chlorine comes from chloros, which means "green." So maybe it's the chlorine. Poisonous, BTW, as a gas. Link to comment Share on other sites More sharing options...

pi_of_9 Posted October 9, 2004 Share Posted October 9, 2004 As I understand, the chemical equation of electrolysis is: 2 H2O -> O2 + 2 H2 and 4 OH- -> O2 + 2 H2O + 4e- at the anode. My question is, are the 4 electrons taken back up by the anode or do they float freely? Is heat created by the reaction? Link to comment Share on other sites More sharing options...
jdurg Posted October 9, 2004 Share Posted October 9, 2004 well, you probably used sodium chloride as electrolyde to made water a conductor. So, when you electrolyse the water, sodium ions comes together with the two electrolites, paper clips for example. The actual substance which turns the water yellow is cloride ions. Halogen ions are 100% completely colorless. They do not, and cannot, produce any color. So I think you mean aqueous elemental chlorine. When you electrolyze a solution of NaCl, you produce sodium hydroxide, hydrogen gas, chlorine gas, and teency, tiny amount of oxygen gas. Link to comment Share on other sites More sharing options...
