Aqueous silver nitrate is subjected to electrolysis, using platinum electrodes. What will be the nature of the solution after some time?

Explanation

At platinum cathode reduction takes place, `Ag_((aq))^(+)+e^(-) rarr Ag_((s))` At platinum anode oxidation takes place, `2H_(2)O_((l)) rarr 4e^(-) +O_(2)+4H_((aq))^(+)`. As a result of the conversion of water to proton, the solution becomes acidic (nitric acid ) The pH of the solution decreases.
