A copper voltameter, a silver voltameter and a water voltameter are connected in series and a current is passed for some time. The ratio of the number of moles of copper, silver andhydrogen formed at the cathode is.

Two voltameters containing copper sulphate and acidulated water respectively are connected in series and the same current is passed for some time. If the amounts of copper and hydrogen obtained at cathode are 0.3177 g and 1.008 xx 10^(-2) g respectively, calculate the of copper. (Eq. mass of hydrogen = 1.008).

The atomic weight of silver and copper are 108 and 64. A silver voltameter and a copper voltameter are connected in series and when current is passed 10.8 gm of silver is deposited. The mass of copper deposited will be

A silver and zinc voltameter are connected in series and a current i is passed through them for a time t liberating W gm of zinc. The weight of silver deposited is nearly

The chemical equivalent of copper and zinc are 32 and 108 respectively. When copper and silver voltameter are connected in series and electric current is passed through for sometimes, 1.6 g of copper is deposited. Then, the mass of silver deposited will be

An electric current is passed through a copper voltmeter and a water voltameter connected in series. If the copper voltameter now weights 16 mg less, hydrogen liberated at the cathode of the water voltmeter measures at STP about

A copper voltameter and water voltameter are connected in series. How much oxygen will be liberated in water voltameter when 0.5 g of copper is deposited in copper voltameter. Chemical equivalent of copper and oxygen are 32 and 8 respectively.

Nichrome and copper wires of same length and same radius are connected in series. Current is I passed through them. Which up more ? Justify your answer.

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)
