5. Calculate the pH of the following buffer solutions: (a) a solution made by dissolving 4.550gKH2PO4 and 1.871gK2HPO4 in water to give 350.mL of solution. Stepwise acid dissociation constants for phosphoric acid may be found in your textbook. (b) a solution made by mixing 35.00mL0.35MN2H4 with 15.00mL0.21MN2H5Cl. The base dissociation constant Kb is 8.50107 for N2H4. Assume that the final volume is the sum of the volunes of the two solutions that are mixed
