Given , for `Sn^(+4) // Sn^(2+)` , standard reduction potential is `0.15` V and for `Au^(3+)//Au` , standard reduction potential is 1.5 V.
For the reaction ,
`3Sn^(2+) + 2 Au^(3+) to 3 Sn^(4+) + 2 Au , ` the value of `E_("cell")^(@)` is ,

A

`+1.35`

B

`+2.55`

C

`-1.35`

D

`-2.55`

Text Solution

Verified by Experts

The correct Answer is:
A
`E_("cell")^(@) = E_("cathode")^(@) - E_("anode")^(@)`
= `1.5 - 0.15 = 1.35 V`
