WebSep 30, 2024 · The numbers of the pH scale come from a formula for the hydrogen ion (H +) concentration. The equation for pH is: pH = -log [H +] The way a logarithmic scale works, chemicals that donate more hydrogen ions (protons) have lower pH values. These are acids. Chemicals that accept hydrogen ions have higher pH values and are bases.
