A current of 2.0 ampere when passed for 5 hours through a molten metal salt deposits 22.2 g of metal of atomic weight 177. The oxidation state of metal in the metal salt is

Options:

Answer:

Solution:

Number of Faraday = number of equivalents.

$\frac{2 \times 60 \times 60 \times 5}{96500} = n \times \frac{22.2}{177}$

Therefore, $n = 3$ .
