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. Webis the standard state concentration = 1 mol/L. So, is a dimensionless number whose logarithm can be defined. In practice, the following formula is used to calculate : where is considered to be given in units of mol / L. In pure (neutral) water at 25 °C the concentration of the hydrogen ion is 10 −7 mol / L. This gives us a of water equal to 7.
