Yes - the salt.You are expecting 2 x H2O -> 2 x H2 + O2 What you are getting is:2 x NaCl + 2 x H2O -> 2 x NaOH + H2 + Cl2.
Actually, to completely balance the reaction:Quote from: another_someone on 26/10/2007 14:36:40Yes - the salt.You are expecting 2 x H2O -> 2 x H2 + O2 What you are getting is:2 x NaCl + 2 x H2O -> 2 x NaOH + H2 + Cl2.So you still get two gases. However, Cl2 can then react with aqueous OH- to form hypochlorite and chloride.Cl2 + 2 OH- → ClO- + Cl- + H2ODick
