“pH has a great importance in our daily life". This can be explained by the following examples-
(i) Plants and animals are pH sensitive: Living organisms can survive only in narrow range of pH change.

(ii) Tooth decay: Change in pH of our mouth causes tooth decay. Tooth decay start when the pH of mouth is lower than 5.5. Tooth enamel gets corroded when the pH in mouth is below 5.5.

(iii) pH is our digestive system: (HCl) Hydrochloric acid is produced by our stomach that helps in the digestion of food. During digestion, if stomach produces too much acid, it will cause pain and irritation.

(iv) pH of the soil: Plants require a specific pH range for their normal growth.
