For goldplating on a copper chain, the substance required in the form of solution is

On passing the current in water voltameter, hydrogen

In water voltameter, the electrolysis of ... takes place

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

A battery of e.m.f. 3 volt and internal resistance 1.0 ohm is connected in series with copper voltameter. The current flowing in the circuit is 1.5 amperes. The resistance of voltameter will be

According to Faraday\'s laws of electrolysis, the amount of decomposition is proportional to

If in a voltaic cell 5 gm of zinc is consumed, then we get how many ampere hours? (Given that E.C.E. of Zn is 3.387 × 10^–7 kg/coulomb)

The current flowing in a copper voltameter is 1.6 A. The number of Cu⁺⁺ ions deposited at the cathode per minute are

In a copper voltameter experiment, current is decreased to one-fourth of the initial value but is passed for four times the earlier duration. Amount of copper deposited will be

A certain charge liberates 0.8 gm of O₂. The same charge will liberate how many gm of silver?
