Aqueous copper sulphate solution and aqu...

Aqueous copper sulphate solution and aqueous silver nitrate solution are electrolysed by 1 ampere current for 10 minutes in separate electrolytic cells. Will the mass of copper and silver deposited on the cathode be same or different ? Explain your answer.

Text Solution

Verified by Experts

Different. According to Faraday.s second law, amounts of different substances liberated by the same quantity of electricity passing through the electrolytic solutions are proportional to their chemical equivalent weights. Since the equivalent weights of copper and silver are different, we shall obtain different masses of copper and silver.

Products of electrolysis depend on the nature of material being electrlysed and the type of electrodes being used. If the electrode is inert (e.g., platinum or gold), it does not participate in the chemical reaction and acts only as source or sink for electrons. On the other hand, if the electrode is reactive, it participates in the electrode reaction. thus, the products of electrolysis may be different for reactive and inert electrodes. Aqueous copper sulphate solution and aqueous silver nitrate solution are electrolysed by 1 ampere current for 10 minutes in separate electrolytic cells.
