Assuming no change in volume , the time required to obtain solution of ph = 12 by electrolysis of 50 mL 0.1 M NaCl (using current of 0.5 amp) will be

4.0 L of a buffer solution is prepared that is 1.0 M NaH_(2)PO_(4) and 1.0 M Na_(2)HPO_(4) . The solution is divided into two halves between two compartments of a cell. Using Pt-electrodes, if current of 1.25 amp. Is passed for 200 minutes, pH of anode compartment is approximately: (Assuming only reaction is electrolysis of water) (Given : pKa_(1)pKa_(2) and pKa_(3) of H_(3)PO_(4) are 3.07, 8.07, 12.07 and log 1.87 = 0.2648 and log 2.16 = 0.344)
