Calculate the pH of the following buffer solutions: (a) a solution made by dissolving 4.969 g KH2PO4 and 1.757 g K2HPO4 in water to give 200. mL of solution. Stepwise acid dissociation constants for phosphoric acid may be found in your textbook. (b) a solution made by mixing 10.00 mL 0.29 M (CH3)2NH with 40.00 mL 0.17 M (CH3)2NH2Cl. The base dissociation constant Kb is 7.40 x 10-4 for (CH3)2NH. Assume that the final volume is the sum of the volunes of the two solutions that are mixed
