On the basis of the electrochemical theory of aqueous corrosion, the reaction occurring at the cathode is:-

Answer»

`O_(2(G))+4H_((aq))^(+)+4e^(-)to2H_(2)O_((l))`
`Fe_((s))toFe_((aq))^(2+)+2E^(-)`
`Fe_((aq))^(2+)toFe_((aq))^(3+)+e^(-)`
`H_(2(g))+2OH_((aq))^(-)to2H_(2)O_((l))+2e^(-)`

SOLUTION :At cathode: `2H_((aq))^(+)+2e^(-)to2H`
`underline(2H+(1)/(2)O_(2)toH_(2)O"")`
`2H^(+)+(1)/(2)O_(2)+2e^(-)toH_(2)O`
