16 Οκτ 2023 · pH is a measure of the concentration of protons (H +) in a solution. S.P.L. Sørensen introduced this concept in the year 1909 . The p stands for the German potenz , meaning power or concentration, and the H for the hydrogen ion (H + ).
Measured on a scale from 0 to 14, pH is based on the concentration of hydrogen ions in a solution. In pure water, which is neutral (neither acidic nor basic), the concentration of hydrogen ions corresponds to a pH of 7.0. This marks the midpoint of the pH scale.
What is the pH scale? The pH scale shows how acidic a substance is. Learn what pH means and how the pH scale s measured in this KS3 chemistry guide.
