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 change as the cause of tooth decay
When we eat food containing sugar,then the bacteria present in our mouth break down the sugar to form acids.This acid lowers the pH in the mouth.Tooth decay starts when the pH of acid formed in the mouth falls below 5.5.This is because then the acid becomes strong enough to attack the enamel of our teeth and corrode it.This sets in tooth decay.The best way to prevent tooth decay is to clean the mouth thoroughly after eating food.
3)Plants and animals are sensitive to pH change
Soil pH and plant growth:Most of the plants grow best when the pH of the soil is close to 7.If the soil is too acidic or basic,the plants grow badly or do not grow at all.The soil pH is also affected by the use of chemical fertilisers in the field.Chemicals can be added to soil to adjust its pH and make it suitable for growing plants.
If the soil is too acidic then it is treated with materials like quicklime or slaked lime.If the soil is too alkaline then alkalinity can be reduced by adding decaying organic matter.
4)Self Defence by animals and plants through chemical warfare
Many animals and plants protect themselves from enemies by injecting painful and irritating acids and bases into their skin.
•When honey bee stings a person,it injects an acidic liquid into the skin.Rubbing with mild base like baking soda solution on the stung area of the skin gives relief.
•When a wasp stings,it injects an alkaline liquid into the skin.Then rubbing with a mild acid like vinegar on the stung area of the skin gives relief.
5) 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.
6) 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.
