Ione faraday of electricity will liberate one gram atom of a metal from a solution of

A

`AuCl_(3)`

B

`CuSO_(4)`

C

`BaCl_(2)`

D

`KCl`

Text Solution

Verified by Experts

The correct Answer is:
D
`KCl hArr K^(+) + Cl^(-)` and `K^(+) + e^(-) rarr K`
Thus, one mole `KCl` need one mole electrons to liberate one gram metal atom. One mole electron charge is equal to `96500 C (1 F)`. Hence, `1 F` charge will liberate one gram atom of metal from solution of `KCl`,
