Three electrolytic cells A, B, C containing solutions of ZnSO₄, AgNO₃ and CuSO₄, respectively are connected in series. A steady current of 1.5 amperes was passed through them until 1.45 g of silver deposited at the cathode of cell B. How long did the current flow? What mass of copper and zinc were deposited?

Question

Three electrolytic cells A, B, C containing solutions of ZnSO₄, AgNO₃ and CuSO₄, respectively are connected in series. A steady current of 1.5 amperes was passed through them until 1.45 g of silver deposited at the cathode of cell B. How long did the current flow? What mass of copper and zinc were deposited?, 15 min, 0.734 g Cu, 0.426 g Zn, 14 min, 1.42 g Cu, 0.43 g Zn, 45 min, 0.426 g Cu, 0.734 g Zn, 60 min, 0.426 g Cu, 0.734 g Zn
