A silver cup is plated with silver by passing 965 coulombs of electricity. The amount of Ag deposited is:
Three faradays electricity was passed through an aqueous solution of iron (II) bromide. The weight of iron metal (at. wt. = 65) deposited at the cathode (in gm) is
Total charge on 1 mole of a monovalent metal ion is equal to
In the electrolysis of water, one faraday of electrical energy would liberate
The volume of oxygen gas liberated at NTP by passing a current of 9650 coulombs through acidified water is:
On passing C ampere of electricity through a electrolyte solution for second. m gram metal deposits on cathode. The equivalent weight E of the metal is
To deposit one equivalent weight of silver at cathode, the charge required will be
