Question:
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 the same or different? Explain your answer.
Solution:
W= itE/96500
= 1×10×60×31.75/96500
Equivalent mass of Cu2+ is different from the equivalent mass of Ag+ so obviously the mass of copper deposited will not be the same as the mass of silver deposited.
