Neutralization
Neutralization

Neutralization, is a chemical reaction, also called a water forming reaction, in which an ,acid, and a base or alkali (soluble base) react and produce a salt and water(H 2 O). In other words, it can be said that ,neutralization, is the combination of hydrogen ions H + and hydroxide ions OH − (or oxide ions O 2−) to form water molecule H 2 O. In the process, a salt is formed.

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 ...
