Question

explain the importance of PH testing in everyday life

Answer 1

Acids and Bases in Organisms. Acids and bases are important in living things because most enzymes can do their job only at a certain level of acidity. Cells secrete acids and bases to maintain the proper pH for enzymes to work. ... This is because enzymes in the small intestine need a basic environment in order to work.The relative acidity or alkalinity of a solution is reported by the pH scale, which is a measure of the concentration of hydrogen ions in solution. Neutral solutions have a pH of 7. A pH of less than 7 denotes acidity (an increased hydrogen… The measurement was originally used by the Danish biochemist S.P.L

Answer 2

ANSWER:

● A scale developed to measure the concentration of hydrogen ions in a solution is known as pH scale where as p in pH implies 'POTENZ' in German.

● pH scale range from 0 (highly acidic) - 14 (highly alkalines).

● The pH value of a neutral solution is 7.

● Acidic solution is represented by a value less than 7 on the pH scale.

● Basic solution is represented by a value greater than 7 on the pH scale.

● An increase in OH- ions concentration in the solution results in increase in the strength of alkali hence, the value of pH increases.

● Acidic giving rise to more H+ ions are strong acid whereas those giving rise less than H+ ions are the termed as weak acid.

● Similarly bases giving rise to more OH- ions are strong bases whereas those giving rise less OH- ions are the termed as weak bases.


IMPORTANCE OF pH VALUE IN OUR LIFE

EXAMPLE:-

◆ pH and plants: proper pH of soil is required for healthy growth of plants. It should not be too Acidic or too Basic

◆ pH value in the digestive system: Human body secrets hydrochloride acid which aids in digestion. Hyperactivity: the condition of excess acid in the stomach. Hyperactivity can be cured by taking ant acid tablets or suspension.
