3 Proportion of undissociated acetic acid as a function of pH. At low pH acetic acid exists as undissociated acid but as the pH rises, an increased proportion of acid dissociates to the acetate anion. 76, the ratio of acid: anion is 1 : 1. , 1973; Babich and Stotzky, 1978; Britz and Tracey, 1990). 3). The antimicrobial activity of weak-acid preservatives depends largely on the concentration of undissociated acid. The pKa value quoted for weak acids indicates the pR at which there is a 1 : 1 ratio of acid : anion.
