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 ?

Options

A. 0.59 V
B. 0.118 V
C. 1.18 V
D. 0.059 V

Answer

A

Explanation

`{:(H_(2)rarr 2H^(+)+2e^(-)),("1 atm 10"^(-10)):}`
`E_(H_(2)//H^(+))=0-(0.059)/(2)log.((10^(-10))^(2))/(1)`
`E_(H_(2)//H^(+))=+0.59V`
