`10800 C` of electricity passed through the electrolyte deposited `2.977g` of metal with atomic mass `106.4 g mol^(-1)`. The charge on the metal cation is

A

`+2`

B

`+3`

C

`+4`

D

`+1`

Text Solution

Verified by Experts

`E=(wxxx96500)/(ixxt)=(2.977xx96500)/(10800)=26.6g "eq"^(-1)`
`therefore "valency" =("atomic weight ")/("Equivalent weight ") =(106.4)/(26.6)=4`
