1.

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.

Answer»

`{:("(i)", "(ii)","(III)","(IV)"),(H_(2), NO_(3)^(-) , OH^(-) , H_(2)):}`
`{:("(i)", "(ii)","(iii)","(iv)"),(Ag, H^(+) , O_(2) , H_(2)):}`
`{:("(i)", "(ii)","(iii)","(iv)"),("Ag", "Ag"^(+) , O_(2) , Ag):}`
`{:("(i)", "(ii)","(iii)","(iv)"),(Ag, H^(+), "Ag"^(+), O_(2)):}`
