products formed
« on: September 18, 2011, 04:36:40 AM »
I want to get myself rectified in the following solution given to the problem:
product of electrolysis of an aquaeous solution of CuCl2 with platinum electrodes.

My answer :

CuCl2   :rarrow: Cu+2  + 2Cl-

At anode, any two of the following has to take place,
2H+  + 2e-    :rarrow: H2      E0 = 0.00
Cu+2 +  2e-  :rarrow: Cu  E0 = 0.34

Thus the following reaction will take place at anode, ( higher value of E0 will be preferred)
Cu+2 +  2e- + H2O  :rarrow: Cu + H+ + OH-

At cathode this reaction will take place,
2Cl-  :rarrow: Cl2 + 2e-


Thus the whole electrolysis reaction is,
Cu+2 + H2O + 2Cl- :rarrow: Cu + H+ + OH- + Cl2

Please correct wherever necessary with explanation. :)
