The hydrogen electrode is dpped in a solution of pH=3 at `25^(@)C`. The potential of the cell would be (the value of 2.303RT/F is 0.059V)

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_H=(-2.303RT)/Flog""1/([H^(+)])`
`=-0.059 (-log[H^(+)])`
`= -0.059 xx pH = -0.059 xx 3 = -0.177V .`
