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^(-) to Ag(s)`
At platinum anode oxidation takes place, `2H_2 O(l) to 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.
