Theoretical pka value of acetic acid

WebbPure acetic acid, known as glacial acetic acid, is a liquid with a density of 1.049 g/mL at 25°C. Calculate the molarity of a solution of acetic acid made by dissolving 35.00 mL of glacial acetic acid at 25°C in enough water to make 400.0 mL of solution. What is the pH of a 0.25 M acetic acid solution if the Ka of acetic acid is 1.8 x 10-5? WebbAcetic acid’s diffusion coefficient is calculated using the change in steady-state current as a function of the rotation rate provided by the Levich equation. The diffusion coefficient of acetic acid according to Equation (9) is found to be 6.47 × 10 − 5 cm 2 s −1, which is consistent with the value of the following literature .
