Ph has a great importance in our daily life justify the statement
Answers
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.
2. pH of the soil. Plants require a specific pH range for their healthy growth.
3. pH in our digestive system. Our stomach produces hydrochloric acid that helps in the digestion of food. During in digestion the stomach produces too much acid that cause pain and irritation.
4. Change in pH causes tooth decay. Tooth decay start when the pH of the mouth is lower than 5.5. Tooth enamel gets corroded when the pH in the mouth is below 5.5.
5. Self-defense by plants and animals through chemical warfare. Bee–sting leaves and acid causing pain and irritation. Applying a mild base like baking soda on the stung area provides relief.
