Calculate the pH for each of the following solutions:
(a) 0.0150 mol HBr are added to 450.0 mL of pure water
(b) 0.0150 mol HBr are added to 450.0 mL of a buffer solution that is 0.120 M H3COOH and 0.115 M CH3COONa. (Ka for CH3COOH is 1.80 x 10-5)
(c) 0.0150 mol HBr are added to 450.0 mL of a buffer solution that is 0.145 M CH3CH2NH2 and 0.165 M CH3CH2NH3Cl. (Kb for CH3CH2NH2 is 5.60 x 10-4)
