Assume that impure copper contains only iron, silver and a gold as impurities. After passage of 140A , for 482.5 sec, of the mass of the anode decreased by 22.260g and the cathode increased in mass by 22.011g . Estimate the % iron and % copper originally present.

In an electrolysis experiment, current was passed for 5h through two cells connected in series. The first cell contains a solution of gold and second contains copper sulphate solution. In the first cell, 9.85g of gold was deposited. If the oxidation number of gold is +3 , find the amount of copper deposited at the cathode of the second cell. Also calculate the magnitude of the current in ampere, ( Atomic weight of Au is 1197 and atomic weight of Cu is 63.5) .

Three electrolytic cells A, B and C containing solutions of zinc sulphate, silver nitrate and copper sulphate, respectively are connected in series. A steady current of 1.5 ampere was passed through them until 1.45 g of silver were deposited at the cathode of cell B. How long did the current flow? What mass of copper and what mass of zinc were deposited in the concerned cells? (Atomic masses of Ag = 108, Zn = 65.4, Cu = 63.5)
