CORRECT statements for electrolysis of aqueous ${\mathrm{AgNO}}_3$ solution with silver electrode is / are
A) Silver deposits at cathode
B) Silver dissolves at anode into solution as ${\mathrm{Ag}}^{+}$ ions

In electrolysis of ${\mathrm{AgNO}}_3$ aqueous solution with silver (Active) electrode
1) Silver deposited at cathode  

${\mathrm{Ag}}_{\mathrm{aq}}^{+}+{\mathrm{e}}^{-}\to {\mathrm{Ag}}_{\left(\mathrm{s}\right)}$
2) Silver dessolves at Anode (Active electrodes)
 ${\mathrm{Ag}}_{\left(\mathrm{S}\right)}\to \mathrm{A}{{\mathrm{g}}^{+}}_{\left(\mathrm{aq}\right)}+{\mathrm{e}}^{-}$
3) As the ${\mathrm{Ag}}^{+}$ ions drawn into solution at anode are deposited at cathode, no change in concentration of ${\mathrm{AgNO}}_3$ solution
