WebMar 5, 2024 · Acidity is measured on a scale called pH, as shown in Figure below. Pure water has a pH of 7, so the point of neutrality on the pH scale is 7. Acidity and the pH Scale Water has a pH of 7, so this is the point of neutrality on the pH scale. Acids have a pH less than 7, and bases have a pH greater than 7. Approximate pHs of examples are shown. WebMar 6, 2024 · pH is an expression of hydrogen ion concentration in water. Specifically, pH is the negative logarithm of hydrogen ion (H +) concentration (mol/L) in an aqueous solution: pH = -log 10 (H +) The term is used to indicate basicity or acidity of a solution on a scale of 0 to 14, with pH 7 being neutral.
