Product Application

Alkalinity Titrimetric Method (0-200 ppm) 

Principle Theory

This test is based on the determination of alkalinity by titration with standard acid to the phenolphthalein color change (or to a pH of 8.3) and to the methyl orange color change (or a pH of 4.3).  For determination of hydroxide alkalinity only, barium chloride is added prior to titration to precipitate the carbonate ions.  Titration is then taken only to the phenolphthalein end point.  A pH meter may be used instead of the indicators to determine the end points of the titration.
