प्रश्न
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.
उत्तर
W = `(itE)/96500 = (1 xx 10 xx 60 xx 31.75)/96500`
Mass of silver will be different because the equivalent mass of Ag is different.
