PH | Definition, Uses, & Facts | Britannica

pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. The term, widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ionwhich ordinarily ranges between about 1 and 10−14 gram-equivalents per litreinto nuers between 0 and 14. In pure water, which is neutral (neither acidic nor …

pH - Wikipedia

where M = mol dm−3. At 25 °C (77°F), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (i.e. have the same concentration of H+ ions as OH− ions, i.e. pure water). The neutral value of the pH depends on the temperature – being lower than
