Will Sn reduce `Sn^(4)+` to `Sn^(2+)` ?
[ Given `E_(Sn^(2+)|Sn)^(@)=0.14V,E_(Sn^(4+)|Sn^(2+))^(@)= 0.15 V`]

Text Solution

Verified by Experts

Since `E_(Sn^(2+)|Sn)^(@)ltE_(Sn^(4+)|Sn^(2+))^(@),` Sn is a sronger reducing agent that `Sn^(4+)` is a sronger oxidising agent than `Sn^(2+)` Hence. Sn will rduce `Sn^(4+)` spontaneously under standard conditions to from `Sn^(2+)`
`Sn(s)+Sn^(4+)(aq)to2Sn^(2+)(aq)`
