Calculate the potential of hydrogen elec...

Calculate the potential of hydrogen electrode in contact with a solution whose pH is 10.

Text Solution

Verified by Experts

For hydrogen electrode, `H^(+)+e^(-)to(1)/(2)H_(2)`.
Applying nernst equation, `E_(H^(+),(1)/(2)H_(2))^(@)=E_(H^(+),(1)/(2)H_(2))^(@)-(0.0591)/(n)"log"(1)/([H^(+)])`
`=0-(0.0591)/(1)"log"(1)/(10^(-10))(pH=10" means "[H^(+)]=10^(-10)M]`
`=-0.0591xx10=-0.591V`
