1.0 L each of a buffer containing 1 mole \[N{{H}_{3}}\] and 1 mol of \[NH_{4}^{+}\] were placed in the cathodic and anodic half-cells and 965 C of electricity was passed. If anodic and cathodic half cells reactions involve oxidation and reduction of water only as \[2{{H}_{2}}O\xrightarrow{{}}4{{H}^{+}}+{{O}_{2}}-4{{e}^{-}};\] \[2{{H}_{2}}O+2{{e}^{-}}\xrightarrow{{}}{{H}_{2}}+2O{{H}^{-}}\] Then pH of

• A. cathodic solution will increase
• B. anodic solution will decrease
• C. both the solutions will remain practically constant
• D. both the solutions will increase
