WebFeb 2, 2024 · As we will see in Section 16, the [In−]/ [HIn] ratio changes from 0.1 at a pH one unit below pKin to 10 at a pH one unit above pKin. Thus most indicators change color over a pH range of about two pH units. We have stated that a good indicator should have a pKin value that is close to the expected pH at the equivalence point. 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 …
