Importance of pH in Everyday Life Are:
a) plants and animals pH sensitive
Our body works within the pH range of 7.0 to 7.8. Living organisms can survive only ina narrow range of pH change. When pH of rain water is less than 5.6, it is called acid rain. When acid rain flows into the rivers, it lowers the pH of the river water. The survival of aquatic life in such rivers becomes difficult.
b)Acids in other planets
The atmosphere of venus is made up of thick white and yellowish clouds
c)pH in our digestive system
It is very interesting to note that our stomach produces hydrochloric acid. It helps in the digestion of food without harming the stomach. During indigestion the stomach produces too much acid and this causes pain and irritation. To get rid ofthis pain, people use bases called antacids. One such remedy must have been suggested by you at the beginning ofthis Chapter. These antacids neutralise theexcess acid. Magnesium hydroxide (Milk of magnesia), a mild base, is often used for this purpose.
d)pH change as the cause of tooth decay
Tooth decay starts when the pH of the mouth is lower than 5.5. Tooth enamel, made up of calcium phosphate is the hardest substance in the body. It does not dissolve in water, but is corroded when thepH in the mouth is below 5.5. Bacteria present in the mouth produce acids by degradation of sugar and food particles remaining in the mouth after eating. The best way to prevent this is to clean the mouth after eatingfood. Using toothpastes, which are generally basic, for cleaning the teeth can neutralise the excess acid and prevent tooth decay.
