What will be the reduction potential of a hydrogen electrode which is filled with HCl solution of pH value 1.0? (at 298 Kelvin)

Options

A. `-59.15V`
B. `+59.15V`
C. `+ 59.15mV`
D. `-59.15mV`

Answer

D

Explanation

`E_(H^(+)//H_2)=E_(H^(+)//H_2)^(@)-(0.05915)/1log""1/([H^(+)])`
`= 0 + 0.05915log[H^(+) ]" volt" = -0.05915` pH
`= -0.05915 xx1 = -0.05915V = - 59.15mV`.
