A biochemist needs 750 mL of an acetic acid–sodium acetate buffer with pH 4.50. Solid sodium acetate (CH₃COONa) and glacial acetic acid (CH₃COOH) are available. Glacial acetic acid is 99% CH₃COOH by mass and has a density of 1.05 g/mL. If the buffer is to be 0.15 M in CH₃COOH, how many grams of CH₃COONa and how many milliliters of glacial acetic acid must be used?

In a solution of 1 M acetic acid, CH₃COOH, 0.25 M of sodium acetate, CH3COONa was added. What is the pH of the solution? (K_a for acetic acid is 1.8 × 10^-5)

The Ka for acetic acid is 1.8 x 10^-5. Calculate the pH of the following buffer solutions: a) 1.5 M CH3COONa/1.9 M CH3COOH b) 0.2 M CH3COONa/0.2 M CH3COOH
