A hydrogen electrode is dipped in a solution at `25^(@)C`. The potential of cell is `-0.177 V`. Calcualte the `pH` of the solution.

A

0.177 V

B

`-0.177 V `

C

0.087 V

D

0.059 V

Text Solution

Verified by Experts

The correct Answer is:
B

`E_(RP) = E_(RP)^(@) + (0.0592)/(1) "log"_(10) [H^(+)]`
`= 0 + 0.0592 xx (-3) = -0.177` V
