In the electrolysis of aqueous sodium chloride solution which of the half-cell reaction will occur at anode ?

Answer»

`Na_((aq))^(+)+e^(-) to Na_((S)),E_(cell)^(THETA)=-2.71V`
`2H_(2)O_((L)) to O_(2(g)) +4H_((aq))^(+)+4e^(-),E_(cell)^(Theta)=-1.23V`
`H_((aq))^(+)+e^(-)to(1)/(2)H_(2(g)),E_(cell)^(Theta)=0.00V`
`Cl_((aq))^(-) to (1)/(2)Cl_(2(g))+e^(-),E_(cell)^(Theta)=1.36V`

SOLUTION :`Cl_((aq))^(-) to (1)/(2)Cl_(2(g))+e^(-),E_(cell)^(Theta)=1.36V`
