Calculate the pH of the following solutions

1. A solution that is 6.0×10−2 M in potassium propionate (C2H5COOK or KC3H5O2 ) and 8.5×10−2 M in propionic acid (C2H5COOH or HC3H5O2 ). The Ka of propionic acid is 1.3×10-5.

2. A solution that is 8.0×10−2 M in trimethylamine, (CH3)3N, and 0.12 M in trimethylammonium chloride, (CH3)3NHCl. The Kb of trimethylamine is 6.4×10-5.

3. A solution that is made by mixing 50.0 mL of 0.16 M acetic acid and 50.0 mL of 0.23 M sodium acetate. The Ka of acetic acid is 1.8×10-5.
