The Importance of pH Measurement-print | Water Tech Online

A solution with a pH of less than 0–6 (i.e., large number of hydrogen ions) is considered acidic, while a pH of 8–14 (i.e., low number of hydrogen ions) is basic. A solution with a pH of 7, equivalent to pure water at 25°C, is considered neutral on the scale. Why Is pH Important?

It is well known that the pH is an important parameter in evaluating the acid–base balance of water. A pH value of 7 is neutral; a pH less than 7 is acidic, and and a pH greater than 7 represents base saturation or alkaline. The principal component regulating ion pH in natural waters is the carbonate, which comprises CO 2, H 2CO 3, and HCO 3 (22).
