What is Acidity?
Definition of Acidity
Acidity is the quantitative expression of water capacity to neutralize a strong base to a designated pH and an indicator of how corrosive water is. Acidity can be caused by weak organic acids, such as acetic and tannic acids, and strong mineral acids including sulfuric and hydrochloric acids; however, the most common source of acidity in unpolluted water is carbon dioxide in the form of carbonic acid. Acidity is classified by the pH value of a titration end point.
