Answer 2

pH plays an important role in our everyday life. A few examples are:-

1. In our digestive system - Hydrochloric acid is produced in the stomach to help in digesting food. However, when the amount of acid exceeds a certain limit it causes acidity and pain. This acidity can be neutralized by taking a mild base called as an antacid.

2. pH of soil – Plants grow only in soils that have a definite pH range. So, highly acidic soils are treated with quicklime or calcium carbonate to reduce its acidity.

3. Tarnished vessels – Copper vessels are tarnished due to the formation of a layer of basic copper oxide. This can be removed when it is rubbed with the citric acid from a lemon. Copper oxide forms copper citrate with citric acid and is washed away giving a shine to the vessels.
