If hydrogen electrodes dipped in two sol...

If hydrogen electrodes dipped in two solutions of `pH=3` and `pH=6` are connected by a salt bridge, the `EMF_(cell)` is

A

0.177V

B

0.3V

C

0.052V

D

0.104V

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(cell)=-0.059log((10^(-6))/(10^(-3)))=-0.059log10^(-3)`
`=0.059xx(-3)=0.177V`.
