The potential of the following cell at 2...

The potential of the following cell at `25^(@)C` is

A

`-0.059V`

B

`0.059V`

C

`-0.59V`

D

`0.5V`

Text Solution

Verified by Experts

The correct Answer is:
c
It is a concentration cell, therefore,`E^(c-)._(cell)=0`
`pH` of `HNO_(3)=-log10^(-1)=1`
`pOH of NaOH=-log 10^(-3)=3`
`:pH of NaOH=14-3=11`
`:. E=-0.059(pH_(c)-pH_(a))`
`=-0.059(11-1)=-0.59V`
