Q 1200091818.     `1.0` ``L each of a buffer containing `1` Mole of `NH_3` and `1` mole of `NH_4^+` were placed in the cathodic and anodic half cells, and `965` `C` of electricity was passed. If anodic and cathodic half cell reactions involve oxidation and reduction of water only as:

`2H_2O → 4H^+ + O_2 + 4e^-`;
`2H_2O + 2e^(-) → H_2 + 2OH^-`;

Then `pH` of anodic and cathodic solutions.


A
