Question

an aqeous solution of AGNO3 is placed in a beaker with twoinert platinum electrodes , when thecell is attached to an externalbattery, electrolysis occurs.asuming a neutral solution and overpotential for O2 and H2 a)what is the reaction that occurs at anode showreasoning b)what is the reaction that occurs at the cathode? c)what are the anode and cathode reactions IF Ag electrodesare used? an aqeous solution of AGNO3 is placed in a beaker with twoinert platinum electrodes , when thecell is attached to an externalbattery, electrolysis occurs.asuming a neutral solution and overpotential for O2 and H2 a)what is the reaction that occurs at anode showreasoning b)what is the reaction that occurs at the cathode? c)what are the anode and cathode reactions IF Ag electrodesare used?

Explanation / Answer

a) oxidation takes place b) reduction takes place   c) at anode : Ag ------> Ag+ +e-     at cathode Ag+ +e- ------> Ag
