Two litre solution of a buffer mixture containing 1.0 M NaH_(2)PO_(4)

1.	Two litre solution of a buffer mixture containing 1.0 M NaH_(2)PO_(4) and 1.0 M Na_(2)HPO_(4) isplaced in two compartments (one litre ineach) of an electrolytic cell. The platinum electrodes are inserted in each compartments and 1.25 ampere current is passed for 212 minute. Assuming electrolysis of water onlu at each compartment. What will be pH in each compartment after passage of above charge ?(pK_(a) for H_(2)PO_(4)^(-)= 2.15.)
