Final answer:
Silver metal will form at the cathode during the electrolysis of aqueous AgNO3 due to the favorable reduction potential for silver ions.
Step-by-step explanation:
During the electrolysis of aqueous AgNO3, the standard reduction potentials are critical to determining what will form at the cathode. According to the standard electrode potentials, the half-reaction for the reduction of silver ions (Ag+) to silver metal (Ag) has a positive potential, which means it is favorable. Therefore, when a silver nitrate (AgNO3) solution undergoes electrolysis, silver metal will form at the cathode as silver ions (Ag+) in the solution gain electrons.
