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. ... So, in order to neutralize the effect of excess acid, a mild base called antacid is usually taken.

Tooth decay can occur when the pH level in the mouth is 5.5. For reference, the neutral level is 7.0. When we consume acidic foods and drinks, the pH within the mouth decreases and can cause the pH in the dental plaque to fall rapidly below 5.0.Mar 28, 2016
