Which will be the proper alternative in place of A in the following equation ?
`2Fe^(+3)+Sn^(+2)to2Fe^(+2)+A`

A

`Sn^(4+)`

B

`Sn^(3+)`

C

`Sn^(2+)`

D

Sn

Text Solution

Verified by Experts

The correct Answer is:
A
`2Fe^(+3)+Sn^(+2)to2Fe^(+2)+A`
Total charge = `2(+3)+(+2)to2(+2)+A`
= `(+6)+(+2)to(+4)+A`
= `(+8)to(+4)+A`
So, A = +4 which is in `Sn^(+4)`
