(b) pH in the digestive system: Human body secrets hydrochloric acid which aids in digestion.
Hyperacidity: The Condition of excess acid in the stomach. Hyperacidity can be cured by taking ant-acid tablets or suspensions.
(c) pH and tooth decay: Tooth enamel which is the hardest substance in our body is corroded when the pH of the mouth is below 5.5. Cleaning of teeth using toothpaste helps in preventing tooth decay.
