What will the product of electrolysis of an aqueous solution of AgNO3 with silver electrodes?

If you have two metal electrodes in its own solution - so silver electrodes and silver ions in solution, then the silver anode will oxidize and those ions that go into solution are then reduced at the cathode. No other reaction occurs.

So, at the silver anode:

Ag - e- --> Ag+ (oxidation)

And at the silver cathode, those same ions that were oxidized are reduced:

Ag+ + e- --> Ag

Stable enough to not react in such conditions. Check the standard electrode potentials.

@ Borek
sir, you mean to say that at anode, the following reaction will take place
H2O   :rarrow: (1/2)O2 + 2H+ + 2e-
