Question

A volume of 100 ml of a buffer of 1 M – NH₃ and 1 M – NH₄⁺ is placed in two half-cells connected by a salt bridge. A current of 1.5 A is passed through the cell for 20 min. If electrolysis of water takes place only and the electrode reactions are:

Right: 2H₂O + O₂ + 4e → 4OH⁻ and Left: 2H₂O → 4H⁺ + O₂ + 4e, then, the pH of the

Accepted Answer

PH of right electrode will increase due to formation of OH– ion.
