Webb26 jan. 2024 · pH is a measure of the concentration of hydronium (H 3 O +) ions in an aqueous solution. It is measured on a negative logarithmic scale from 0 to 14. Acidic solutions are below pH 7, with 0 being the most acidic. Basic solutions are above pH 7, with 14 being the most basic. A solution with a pH of 7 is considered neutral. WebbThe pH of a substance is a measure of how acidic or basic the substance is. 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.
