pH is defined as the negative logarithm of the molar concentration of the hydrogen ion. The pH scale ranges from 0 to 14. Pure water is neutral with a pH of 7; pH less than 7 is acidic, and pH greater than 7 is basic. Since the pH scale is logarithmic, a unit decrease in pH equals a ten-fold increase in acidity.
