Alkalinity Water Test
Product code RXSOL-60-5515-003
Alkalinity TEST FOR BOILER and COOLING WATER
Description
In cooling water systems, alkalinity is of major importance since the total alkalinity of a water is one factor that must be considered when predicting the tendency for the water to precipitate calcium carbonate scale. Depending on the choice of chemical treatments to protect against corrosion and scale formation, the operating alkalinity and pH ranges are chosen to balance these two features.

Application
Procedure:
. 20 drops of sample water was taken in a dry test tube with a calibrated pipette.
. Adding 1 drop of Phenolphthalein indictor.
. Adding HCl with a calibrated pipette till the colour of the solution changes from pink to colourless.
Precautions
Avoid contact with EYE / Hand and other CHEMICALS and Gases.
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.
