A current of 2.0A passed for 5 hours through a molten metal salt deposits 22.2 g of metal (At. Wt. =177). The oxidation state of the metal in the metal salt is

A

`+1`

B

`+2`

C

`+3`

D

`+4`

Text Solution

Verified by Experts

The correct Answer is:
C
`E = (W)/(Q) xx 96500 = (22.2)/(2 xx 5 xx 60 xx 60) xx 96500 = 59.5`
Ox.state = `("At.mass")/("Eq. mass") = (177)/(59.5) = 3`.
