Webb25 jan. 2024 · pH in Chemistry is used to measure the acidity or basicity of an aqueous solution. The full form of pH is the Potential of Hydrogen. It is the negative logarithm H+ion concentration. Students can measure the pH value by using a pH scale. The pH scale ranges from 0 to 14 in water. pH 7 is neutral. Webb10 logarithm (i.e. the decimal logarithm) of the molar concentration of hydrogen ions in the solution. More precisely, pH is the negative of the base 10 logarithm of the activity of the H+ ion. At 25 °C, solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic.
