Acidity And Alkalinity - Water Quality - Dr. Darrin Lew

10/4/2021, · Background. The alkalinity of water is its acid-neutralizing capacity. ,The acidity, of water is its base-neutralizing capacity. Both parameters are related to the buffering capacity of water (the ability to resist changes in pH when an acid or base is added). Water with high alkalinity can ,neutralize, a large quantity of acid without large changes in pH; on the other hand, water with high ...
