Q. Explain the importance of pH testing in everyday life?
Ans: The measure of hydrogen ion concentration used to determine the acidity or alkalinity of a solution is known as pH.
The following is the equation for calculating the pH:
-log[H+] = pH
pH value:
A pH scale is used to determine the pH value of a component. The pH scale ranges from 0 to 14, with 0 indicating extremely acidic and 14 indicating extremely alkaline.
If a pH value of 7 is found in any solution, it indicates that the solution is neutral in nature. Values of less than 7 suggest an acidic solution, whereas values of more than 7 indicate an alkaline solution.
Importance of pH of testing in every day life:
- All physiological responses in the human body take place at a pH of 7-7.8. In our digestive tract, pH is crucial.
- Hydrochloric acid is secreted in the stomach as food enters the stomach. It raises the pH of the stomach to a range of 1 to 3.
- The activation of the enzyme pepsin, which aids in the digestion of protein in food, is dependent on this pH.
- when the mouth’s pH drops below 5.5. Our teeth begin to decay.
- Toothpaste and tooth powder are natural products that are used to clean teeth.
