An electric current of `0.4 A` is passed through a silver voltmeter for half an hour.Find the amount of silver deposited on the cathode. `ECE` of silver `= 1.12 xx 10^(-4) kg C^(-1)`

Text Solution

Verified by Experts

Using the formula `m = Zit`, the mass of silver deposited
`= (1.12 xx 10^(-6) kg C^(-1) (0.4 A) (30 xx 60 s)`
`=8.06 xx 10^(-4) kg = 0.806 g`.
