The full form of PH is Potential of Hydrogen. ... PH describes the concentration of the hydrogen ions in a solution and it is the indicator of acidity or basicity of the solution. The pH value on a pH-scale varies from 0 to 14.

pH plays a very important role in our everyday life. 1. In our digestive system :Hydrochloric acid produced in our stomach helps the digestion of food without causing any harm to the stomach. But when the amount of the acid goes beyond a certain limit due to indigestion, pain and irritation are created in the stomach.

Bacteria in the mouth create acids after eating through the oxidation of sugar and food particles in the mouth. Tooth decay starts when the mouth's pH is below 5.5. ... Since plaque coats the teeth, saliva can not reach the tooth layer to neutralize the acid.
