1.	50 ml of a buffer of 1 M NH3 and 1 M NH4 + are placed in two volatic cells separately. A current of 3.0 amp is passed through both cells for 10 min. If electrolysis of water takes place as2H2O + O2 + 4e– →4OH– (R.H.S.) 2H2O →4H+ + O2 + 4e– (L.H.S.)then pH of the (1) L.H.S. will increase (2) R.H.S. will increase (3) R.H.S. will decrease (4) Both side will increase
Answer» Correct option (2) R.H.S. will increase Explanation: Because of the reactions of electrolysis, [H⁺] concentration will decrease as a result of which pH will increase.
