Home; … WebKacetetic acid = (H+) (Ac-1)/ (Hac) pK of acetic acid is 4.74 note pKa= -log ( Kacetic acid ) solving means kacetic acid = 1.82 x10–5 (WE WILL NEED THIS NUMBER) Part 2 The Ac- acetate is in equilibrium with the water. Ac- +H2O= HAc +OH- This equation (2) is kacetate= (Hac) (OH-)/ (Ac- ) (H2O)

WebBecause 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 … Web28 apr. 2024 · We are given the pKa for butyric acid and asked to calculate the Kb and the pKb for its conjugate base, the butyrate ion.
