Question
Predict the products of electrolysis in each of the following:
(i) An aqueous solution of AgNO3 with silver electrodes.
ii)An aqueous solution AgNO3 with platinum electrodes.
iii) A dilute solution of H2SO4 with platinum electrodes.
iv) An aqueous solution of CuCl2 with platinum electrodes.
Solution
At cathode Ag+ +e- → Ag
silver is deposited.
At anode= NO3- ions move, Dissolve,equivalent amount of Ag concentration AgNO3 remains unchanged.
ii) At cathode: Ag will be liberated.
At anode: O2 gas will be liberated.
iii) At anode:O2 gas will be liberated.
At cathode: H2 gas will be liberated.
iv) At cathode: Cu will be liberated
At anode: Cl2 gas will be liberated.
