Does electrolizing tap water cause the chlorine in it to become gaseous and therefore creating chlorine gas?

Question

I am trying to get some hydrogen and oxygen from water and I want to make sure it is safe. I know they "purify" tap water by adding chlorine to it, so does the electrolisizing process make this experiment deadly?

Answer 1

No. Cl2 has an oxidation number of 0, so it's already in the water to some extent. Cl2 + H2O ===> HClO + HCl, but the [Cl-] is there in too small an amount. So go ahead.
