Calculate E(cell) for Cr|Cr^(3+)||Cr^(3+...

Calculate `E_(cell)` for `Cr|Cr^(3+)||Cr^(3+)|Cr`:

A

`(0.028V)`

B

`(0.083)`

C

`(0V)`

D

`(0.125)`

Text Solution

Verified by Experts

The correct Answer is:
A
`E= (0.059)/(3) log ([Cr^(3+)]R.H.S)/([Cr^(3+)]L.H.S) = (0.059)/(3) log(1)/([0.04]) = 0.028 V`
`Cu^(2+) (aq) + 2e^(-) rightarrow Cu(s)`
