Question

Part A)

Calculate the pHpH of a solution that is 0.065 MM in potassium propionate (C2H5COOKC2H5COOK or KC3H5O2KC3H5O2) and 0.090 MM in propionic acid (C2H5COOHC2H5COOH or HC3H5O2HC3H5O2).

Express your answer to two decimal places.

Part B)

Calculate the pHpH of a solution that is 0.080 MM in trimethylamine, (CH3)3N(CH3)3N, and 0.11 MM in trimethylammonium chloride, ((CH3)3NHCl(CH3)3NHCl).

Express your answer to two decimal places.

Part C)

Calculate the pHpH of a solution that is made by mixing 50.0 mLmL of 0.14 MM acetic acid and 50.0 mLmL of 0.20 MM sodium acetate.

Express your answer to two decimal places.
