Equal quantity of electricity is passed through three electrolytic cells containing aqueous solutions of \( \mathrm{FeCl}_{3} \), \( \mathrm{Fe}_{2}\left(\mathrm{SO}_{4}\right)_{3} \) and \( \mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3} \). Regarding the electrolytic process, which of the following is/ are correct, assuming at cathode, only iron is reduced?
(a) The amount of iron deposited in three cases is equal
(b) The amount of iron deposited in \( \mathrm{Fe}_{2}\left(\mathrm{SO}_{4}\right)_{3} \) and \( \mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3} \) is equal
(c) Same gas is evolved at anode in all three electrolytic processes
(d) Amount of iron deposited in \( \mathrm{Fe}_{2}\left(\mathrm{SO}_{4}\right)_{3} \) is double than that of iron deposited in case of \( \mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3} \)
