State Faraday’s first law of electrolysis. Calculate the charge required in terms of Faraday for the reduction of 1 mole of Cu2+ to Cu.

Answer»

Faraday’s first law of electrolysis : The amount of any substance deposited or liberated at the electrode is directly proportional to the quantity of electricity passing through the electrolyte.

Cu2+ + 2e  Cu

:. Quantity of charge required for reduction of 1 mol of Cu2+ = 2F
