WebMay 6, 2024 · By. Anne Marie Helmenstine, Ph.D. Updated on May 06, 2024. pH is a logarithmic measure of the hydrogen ion concentration of an aqueous solution pH = -log [H +] where log is the base 10 logarithm and [H +] is the hydrogen ion concentration in moles per liter. pH describes how acidic or basic an aqueous solution is, where a pH below 7 is … 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. canadian grants for window replacement https://karenneicy.com
