Apparatus :

1Test Tube
1 Titrator

Reagents :

1 Bottle Phenolpthalein (15ml)
1 Bottle Indicator
1 Bottle 0.1N Sulphuric Acid (50ml)

Procedure :

The test kit is designed to run both 'P' and 'M' Alkalinities. For standard boiler water treatment only the 'P' Alkalinity need be run.

* Fill the Test Tube to 10ml. mark with test sample.
* Add 3 drops of phenolphthalein to test sample. Insert Test Tube cap and mix. If no red colour develops, 'P' Alkalinity is 'Zero' and treatment should be added.
* If red colour appear, fill Titrator with Sulphuric Acid 0.1N to the Zero mark.
* Insert the titrator in the Test Tube cap, and add Sulphuric Acid with shaking, until the red colour disappears.
* Result is obtained by multiplying Titrator reading by a factor of 25. The result is in p.p.m. Calcium Carbonate
