electrolysis, calcium chloride
« on: December 15, 2008, 02:11:07 PM »
The anode reaction is 2Cl- -> Cl2 (g) + 2e-   
and the cathode reaction is Ca2+ + 2 e- -> Ca(s)
Is this correct, or have I mixed these up?

yes correct for electrolysis of molten calcium chloride. Always remember Anode is Oxidation and Cathode is where reduction takes place and you won't go wrong.

Just my silly way of memorizing, AO = Atomic Orbital = Anode Oxidation.   CR = Cathode Ray = Cathode Reduction. If it doesn't make any easier for you just forget it. :-\
