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

Answer

B

Explanation

`H_(2)to2H^(+)+2e^(-)`
`E_("oxi")=E_("oxi")^(@)-(0.059)/(2)"log"([H^(+)]^(2))/(P_(H_(2)))`
`=0-(0.059)/(2)"log"([10^(-10)]^(2))/(1)`
`=-(0.059)/(2)xx(-20)`
`=0.59 V`
