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_("metal")=("Weight of metal"xx96500)/("Number of coulomb")=(22x96500)/(2xx5xx60xx60)=59.5`
Oxidation number of the metal`=(177)/(59.5)=+3`.
