WHAT IS IT?
pH, commonly used for water measurements, is a measure of acidity and alkalinity, or the caustic and base present in a given solution. It is generally expressed with a numeric scale ranging from 0-14. The value 7 represents neutrality. The numbers on the scale increase with increasing alkalinity, while the numbers on the scale decrease with increasing acidity.
Each unit of change represents a tenfold change in acidity or alkalinity. The pH value is also equal to the negative logarithm of the hydrogen-ion concentration or hydrogen-ion activity. pH values for some common solutions are listed in the table to the right.
How Are pH Measurements Used?
pH measurements are widely used to control processes, ensure product quality and safety.
pH neutralization of effluent in industrial manufacturing environments
Cooling tower and boiler control
Food and beverage quality control and safety
Upstream protection of filtration membranes
Water pre-treatment for manufacturing processes
Swimming pool control
Pulp and paper manufacturing
Pharmaceutical research & development and manufacturing
Blood-gas analysis in medical devices
