Importance Of pH In Everyday Life
Do you know why it is advised to clean your mouth after consuming food?
Acids are produced in the mouth due to the degradation of sugar and food particles by certain bacteria. As a result, the pH of mouth is lowered.
pH is the measure of the acidity or alkalinity of a solution. The pH scale varies from 0 to 14. A pH value from 0 to 6.9 represents an acidic solution, whereas a pH value from 7.1 to 14 represents a basic solution. A pH value of 7 represents neutral solutions.
Tooth enamel, which is made of calcium phosphate, is sensitive to pH.It does not dissolve in water (neutral pH), but gets corroded when pH in the mouth is below 5.5.
Hence, tooth decay starts when the pH of mouth is lower than 5.5.
Do You Know:
Toothpastes used by us for cleaning our teeth are generally basic in nature. Hence, it can neutralize excess acid present in the mouth and prevent tooth decay.
Let us study the role of pH in our daily life.
All living organisms are pH sensitive and can survive only in a narrow range of pH.
the importance of pH in daily life are:
Are plants and animals pH sensitive? Our body works within the pH range of 7.0 to 7.8. Living organisms cansurvive only in a narrow range of pH change. When pH of rain water isless than 5.6, it is called acid rain. When acid rain flows into the rivers, itlowers the pH of the river water. The survival of aquatic life in such riversbecomes difficult.
What is the pH of the soil in your backyard? Plants require a specific pH range for their healthy growth.
pH in our digestive system It is very interesting to note that our stomach produces hydrochloricacid. It helps in the digestion of food without harming the stomach.During indigestion the stomach produces too much acid and this causespain and irritation. To get rid of this pain, people use bases calledantacids. One such remedy must have been suggested by you at thebeginning of this Chapter. These antacids neutralise the excess acid.Magnesium hydroxide (Milk of magnesia), a mild base, is often used forthis purpose.
pH change as the cause of tooth decay Tooth decay starts when the pH of the mouth is lower than 5.5. Toothenamel, made up of calcium phosphate is the hardest substance in thebody. It does not dissolve in water, but is corroded when the pH in themouth is below 5.5. Bacteria present in the mouth produce acids bydegradation of sugar and food particles remaining in the mouth aftereating. The best way to prevent this is to clean the mouth after eatingfood. Using toothpastes, which are generally basic, for cleaning the teethcan neutralise the excess acid and prevent tooth decay.
Self defence by animals and plants through chemical warfare Bee-sting leaves an acid which causes pain and irritation. Use of a mild base like baking sodaon the stung area gives relief. Stinging hair of nettle leaves inject methanoic acid causing burning pain.
The balance of alkaline and acids (pH) in your body is very important. It: helps you digest your food (stomach acid)regulates your breathing rate (carbonic acid in your blood)controls microorganisms on your skinactivates enzymes
Your blood has a pH which needs to be maintained between 7.35 and 7.45, or else serious illness and death may occur. Your stomach has a regulated pH of hydrochloric acid which is essential in digesting foods.Wasps and jellyfish have an alkaline sting, and bees have an acidic sting. Therefore with wasps there stings can be treated with vinegar, and bees with soap
