What is pH its definition and measurement.

pH (potential of Hydrogen) measurement is used to check it out whether the solution is acidic or alkaline. If the solution is detected with equal amount of alkaline (basic) or acidic then the pH is considered as neutral. Acidity and alkalinity can be determined by measuring the concentration of hydrogen ions in the given liquid solution. As the concentration of hydrogen ions decreases the water becomes basic and as the concentration increases the water becomes acidic.

Why Measurement of pH is necessary?

Many processes containing water have a need for measurement for pH. Most of the things depends on a proper level of pH. The blood which is flowing in human body through veins must have a pH of 7.35 and 7.45. If pH exceed thin range by a little one-tenth of a pH unit could prove fatal.

Applications of pH

Control of Proper pH keeps milk from turning sour, makes strawberry jelly gel, and it also prevents shampoo from stinging to your eyes.Other application of pH are as follows:
  • It is used in neutralization of effluent in steel, paper or pulp, chemical, and pharmaceutical manufacturing.
  • Hexavalent chromium destruction
  • Cyanide destruction
  • Reverse osmosis
  • Odor scrubbers
  • Used in Pharmaceutical manufacturing
  • In manufacturing of chemical and petrochemical
  • Used in cooling tower control
  • Food processing
  • Coal industry
  • Plating waste treatment
These are some points where pH is used in day to day life.
