Three faraday of electricity is passed through molten solutions of `AgNO_3` , `NiSO_4` and `CrCl_3` kept in three vessels using inert electrodes. The ratio in mol in which the metals Ag, Ni and Cr will be deposited is-

Options

A. `1:2:3`
B. `3:2:1`
C. `6:3:2`
D. `2:3:6`

Explanation

To determine the ratio in which the metals Ag, Ni, and Cr will be deposited when 3 Faraday of electricity is passed through their respective molten solutions, we can follow these steps:

### Step 1: Understand the Electrolysis Reactions
1. **Silver (Ag) from AgNO₃**: The half-reaction for the reduction of silver ions is:
\[ \text{Ag}^+ + e^- \rightarrow \text{Ag} \]
This means that 1 mole of Ag is deposited for every 1 Faraday of charge.
