Question Asked by a Student from EXXAMM.com Team

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

cathodic solution will increase

B

anodic solution will decrease

C

both the solutions will remain practically constant

D

both the solutions will increase
