Electrolysis of an aqueous solution of `AgNO_(3)` with silver electrodes produces `ul((i))` at cathode while `ul((ii))` ions are dissolved from anode. When Pt electrodes are used `ul((iii))` is produced at anode and `ul((iv))` at cathode.

Options

A. `{:("(i)", "(ii)","(iii)","(iv)"),(H_(2), NO_(3)^(-) , OH^(-) , H_(2)):}`
B. `{:("(i)", "(ii)","(iii)","(iv)"),(Ag, H^(+) , O_(2) , H_(2)):}`
C. `{:("(i)", "(ii)","(iii)","(iv)"),("Ag", "Ag"^(+) , O_(2) , Ag):}`
D. `{:("(i)", "(ii)","(iii)","(iv)"),(Ag, H^(+), "Ag"^(+), O_(2)):}`

Answer

C
