Topic: pH scale and its day to day application
Definition: pH scale is the scale developed to measure the concentration of Hydrogen ion in a solution. Here ‘p’ in pH implies ‘potenz’ in german. The pH of a neutral solution is 7. for Acidic solution pH is less than 7 and for basic solution pH is greater than 7.
Application of pH in day to day life:
|1.||Digestion||Release of HCL in stomach to create acidic environment and eventually leading to breaking of food.|
|2.||Tooth decay||If pH reaches below 5.5, tooth decay starts. Best way is to rinse mouth thoroughly after consuming food.|
|3.||Agriculture||Plants grow best in neutral condition. If pH<7 add quick lime or slaked lime. If pH>7 then add decaying organic matter.|
|4.||Self defence by animal and plants||Protection by injection of acid and bases. For example When honey bee stings a person , it inject an acidic liquid into the skin. Rubbing with mild base like baking soda solution on the stung area of the skin gives relief.|
