Write down the reaction equations for the cathodic and anodic processes occurring during electrolysis

Write down the reaction equations for the cathodic and anodic processes occurring during electrolysis with graphite electrodes of aqueous solutions of the following substances: silver (I) nitrate.

The electrolysis of silver nitrate takes place with the release of metal at the cathode (negative electrode) and the release of oxygen at the anode (positive electrode). Since silver is an electrically positive metal relative to hydrogen, it will be released at the cathode before the water decomposes. Silver potential +0.799 V, hydrogen zero conditionally 0 V.

Let’s describe the individual stages:

Cathode part: silver ions move to it, Ag (+) + 1e = Ag

Anode part: decomposition of water, 2H2O – 4e = O2 + 4H (+)

Overall reaction: 4AgNO3 + 2H2O = 4Ag + O2 + 4H (+) + 4NO3 (-)
