A hydrogen gas electrode is made by dipping platinum wire in a solution of HCl or `pH = 10` and by passing bydrogen gas around the platinum wire at one atm pressure . The oxidation potential of electrode would be ?

A

1.81 V

B

0.059V

C

0.59V

D

0.118V

Text Solution

Verified by Experts

The correct Answer is:
C
`(1)/(2)H_(2)(g)toH^(+)+e^(-)`
`E_(O.P.)=E_(O.P.)^(o)-(0.059)/(n)log([H^(+)])/((P_(H_(2)))^(1//2))`
`E_(O.P.)=0-(0.059)/(1)"log"(10^(-10))/((1)^(1//2))(pH=10,[H^(+)]=10^(-10)M)`
`E_(O.P.)=0.59V`
