Half equation for electrolysis of chlorine
WebThe half equation is: Cu 2+ (aq) + ? → Cu (s) So the electron balance is Cu 2+ + 2e - → Cu (s) Or Cu 2+ → Cu – 2e - At the anode Rule 2 says halogen (Cl) forms at the anode and not hydroxide (OH - ). So at the anode, electrons are taken away from the chlorine. Web(1 mark) (b) (i) At which electrode, the anode or the cathode, does chlorine form during electrolysis?
