1) In the process of digestion:-
In stomach the enzymes would work only if the pH of the stomach secretion Is acidic.
some time the secretion increases more than required that time indigestion occur.
To cure this we use medicine made up of bases i.e., Magnesium Hydroxide or Sodium bicarbonate.
2)pH in our mouth:
When we eat the medium of our mouth became acidic.
If more acidic medium will occur than our tooth decay start.
To cure this we use toothpaste which contains slightly basic.which helps to prevent tooth decay by neutralising the excess acid in our mouth.
3)Self defense by animals and palnts:
Some plants and animals like BEE(sting acid),WASP(sting alkaline) as insect & NETTLE(sting acid) as plant sting their acids in the person's body causing immense & burning pain.
To cure this when BEE or NETTLE sting occur we should use baking soda.
For curing the WASP sting we should use Vinegar etc.

Importance of pH in everyday life
1)pH in our digestive system
Our stomach produces hydrochloric acid.This dilute hydrochloric acid helps in digesting our food without harming the stomach.Sometimes excess of acid is produced in the stomach.The excess acid in the stomach causes indigestion which produces pain and irritation.In order to cure indigestion,we can take bases called antacids.Being basic in nature,antacid react with excess acid in the stomach and neutralises it.
The two common antacids are Milk of Magnesia (Magnesium Hydroxide)and Sodium Bicarbonate(Baking soda)
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.
