What is the potential of a cell containing hydrogen electrodes, the negative one in contact with `10^(-10) M H^(+)` and positive one in contract with `0.025MH^(+)`?

A

0.18 V

B

0.28 V

C

0.38V

D

0.48V

Text Solution

Verified by Experts

The correct Answer is:
C
`(1)/(2)H_(2)toH^(+)(10^(-8)M)+e^(-)` (oxidation)
`H^(+)(0.025M)+e^(-)to(1)/(2)H_(2)` (reduction)
Cell reaction is:
`H^(+)(0.025M)toH^(+)(10^(-8)M),E_(cell)=0.38V`
