The correct statement about the electrolysis of an aqueous solution of AgNO3 with Ag electrode is:

1. Ag+ ion gets oxidised at cathode; Ag(s) is reduced at anode.
2. H2O gets reduced at cathode; H2O gets oxidised at anode.
3. Ag+ ion gets reduced at cathode; H2O is oxidised at anode.
4. Ag+ ion gets reduced at cathode; Ag(s) is oxidised at anode.

Hints

From the following, identify the reaction having the top position in the EMF series (standard reduction potential) according to their electrode potential at 298 K.

1. Mg2++ 2e → Mg(s) 2. Fe2+ + 2e →  Fe(s)
3. Au3++ 3e → Au(s) 4. K++ 1e → K(s)
