Application of pH measurement in Industry:
pH measurement is essential in :
1) Waste water treatment, municipal sewage treatments.
2) Boiler feed water treatment.
3) Drinking water purification.
4) Production of Ultra pure water.
5) Aquariums and swimming pools.
6) Cooling tower water.
7) Checking freshness of raw incoming milk.
8) Desulphurization process that removes sulfur from oil in oil refineries.
9) Process of drying in textile industries.
10) Checking chemical reaction in production of drugs.
11) Determining plant nutrients in soil.
12) Digestion and bleaching processes in the manufacturer of pulp and papers.
Effect of pH on electrical Conductivity:
The conductivity of solution depends upon the concentration of all the ions presents. The conductivity increases with increase in concentration of ions. These ions contribute differently to the conductivity depending upon their mobilities through the solution. The most mobile cation is the hydrogen ion [H+ ]. pH is measurer of the concentration of the hydrogen ions for an acidic solution, Thus solutions having lower pH values are having higher conductivity values.
