Q19. Write the importance of pH in :
(a) Tooth decay
(b) Agriculture
(c) In digestion of food.
Answers
Answer:
Answer. The suger present between our teeth is break down by bacteria to form acid (lactic acid). When the pH value of our tooth is below 5.5, our tooth start decaying. Digestion is effected by pH under normal circumstances the pH value of our stomach is 1.4 in case when its pH value reduces we suffer from acidity
Answer:
Tooth decay
The suger present between our teeth is break down by bacteria to form acid (lactic acid). When the pH value of our tooth is below 5.5, our tooth start decaying.
Digestion
Digestion is effected by pH under normal circumstances the pH value of our stomach is 1.4 in case when its pH value reduces we suffer from acidity.
Agriculture
It is a measure of the acidity or alkalinity of a soil. The study of soil pH is very important in agriculture due to the fact that soil pH regulates plant nutrient availability by controlling the chemical forms of the different nutrients and also influences their chemical reactions.
