Question

Give two applications of pH in our daily life.

Answer 1

pH scale: the pH scale is logarithmic, indicating the concentration of hydrogen ions in a solution in inverse order.

1. pH is a measure of how acidic/basic water is.
2. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
3. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

Application of pH in our daily life:

1. In our digestive system: Hydrochloric acid produced in our stomach helps the digestion of food without causing any harm to the stomach.
2. Acids cause tooth decay: When we eat sugary food, it gets degraded by bacteria present in the mouth, and acid is formed.
