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 .

WebbBecause of the very large range of acid strengths ( greater than 10 40), a logarithmic scale of acidity ( pK a) is normally employed.Stronger acids have smaller or more negative pK a values than do weaker acids. A discussion of acid-base terminology is available here. The pK a values given here are extrapolated for water at 25 ºC. Many of the pK a values given … Webb0.5 M is a fairly concentrated solution that promotes greater dissociation of acetic acid than expected, and results in a higher Ka / lower pKa. The pKa of acetic acid in a very dilute solution is 4.75 like you indicated, but the pKa of acetic acid in a 0.1 M solution of ions is lowered to 4.56 and will change as the ion concentration increases ... highlights oxford
