The dissociation constant of a weak acid HA is given by: Ka = [H+] [A-] / [HA] WebThe acid dissociation constant (Ka) is a measure of the extent to which an acid dissociates in solution and therefore its strength. ... (HCl) is a strong acid with a dissociation constant of approximately 1.0 x 10^6, while acetic acid (CH3COOH) is a weak acid with a dissociation constant of approximately 1.8 x 10^-5.
WebApr 11, 2024 · Note: When we consider the theoretical values of acidity of formic acid and acetic acid, p H is 2.3 for formic acid and 2.8 for acetic acid. If the p H value is more, then the acidity is less. It can also be determined by p K a value. p K a of acetic acid is 4.8 while that of formic acid is 3.8.
