The standard electrode potential for the reactions,
`Ag^(+)(aq)+e^(-) rarr Ag(s)`
`Sn^(2+)(aq)+2e^(-) rarr Sn(s)`
at `25^(@)C` are `0.80 ` volt and `-0.14 ` volt, respectively. The `emf`of the cell `Sn|Sn^(2+)(1M)||Ag^(+)(1M)Ag` is `:`

A

`0.66` V

B

0.80 V

C

0.94 V

D

1.08 V

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(cell)^(@) = E_(RP_(Ag))^(@) - E_(RP_(Sn))^(@)`
`= 0.80 - (-0.14) = 0.94` V
