Question

What is ph value. Write its importance

Answer 1

Answer:

The significance of the pH value. pH is a measure of the acidic or basic (alkaline) nature of a solution (concentration of the hydrogen ion [H+] activity in a solution determines the pH). The pH scale ranges from 0 to 14, which is the most acidic, a pH of 7 is neutral, and 14 is the most alkaline.

Answer 2

pH Scale :-

The strength of an acid or base is measured on a scale of numbers ranging from 1 to 14 . This scale of numbers is called the pH scale. The acids have a pH between 1-6 , and bases have a pH between 8-14 . The substances having pH 7 are neutral in nature, and are basically salts.

Importance of pH scale :-

• pH helps us to differ between acids and bases.
• pH of gastric juices in the stomach is important in the process of digestion.
• pH changes in our mouth can become a cause of tooth decay.
• The growth of plants and survival of animals also depends on the proper maintenance of pH.
