WebAug 14, 2015 · Once the $\mathrm{p}K_{\mathrm a}$ is known, the equation will tell you the ratio of acetate to acetic acid (ethanoic acid). The ratio changes at various $\mathrm{pH}$ values. The $\mathrm{p}K_{\mathrm a}$ is 4.76, so for a $\mathrm{pH}$ below 3.75 the dominant species in solution will be acetic acid; at pH 5.76, the dominant species in ... WebIn the case of acetic acid, for example, if the solution's pH changes near 4.8, it causes a large change in the presence of acetic acid. When the pH is 3.8, over 90 % exist as acetic acid molecules (CH 3 COOH), but at a pH of 5.8, over 90 % exist as acetate ions (CH 3 COO-). Conversely, to change the pH level near the pKa value of an acid, the dissociation status …
