When electrolysis of silver nitrate solution is carried out using silver electrodes, wich of the following reaction occurs at the anode?

Options

A. `Ag to Ag^(+) + e^(-)`
B. `Ag^(+) + e^(-) to Ag`
C. `2 H_(2)O to 4 H^(+) + O_(2) + 4 e^(-)`
D. `4 OH^(-) to 2H_(2) + O_(2) + 4 e^(-)`

Answer

A

Explanation

At the anode , Ag is oxidized most easily (or `NO_(3)^(-)` ions attack Ag electrode to convert it into `Ag^(+)` ions ) .
