The pH scale measures the degree to which a liquid is either acidic or alkaline. A pH value of 7 is considered neutral while a pH of 1 is highly acidic and a pH of 14 is highly alkaline. The measurement of pH is one of the most frequently performed water quality determinations. Many chemical processes and operations depend on the careful measurement and control of pH.
