Alkalinity Test
The normal conditions of the alkalinity of natural waters are associated with
the carbon dioxide, bicarbonate, carbonate and hydroxide components.
These factors are characteristic of the source of water and the natural
processes taking place at any given time. For particular industrial and
domestic use, it is often desirable to change these characteristics by
treatments such as aeration, neutralization, softening, etc. The particular
treatment and the extent to which it is employed will depend upon the end
use of the water.
Alkalinity of a water is determined by titration with a standard acid to
successive indicator endpoints, thus permitting the calculation of the various
forms of alkalinity.
Field Test Method
Quantity Contents Code
15 mL Total Alkalinity Indicator 2786-E
100 Phenolphthalein Tablets T-2246-J
30 mL *Alkalinity Titration Reagent B *4493-G
1 Test Tube, 5-10-15 mL, glass, w/cap 0778

WARNING: Reagents marked with a * are considered to be potential health hazards.
To view or print a Material Safety Data Sheet (MSDS) for these reagents see MSDS CD

The alkalinity titration tube is calibrated so that the result can be read
directly from the scale on the titrator in ppm calcium carbonate (CaCO
3
).
The result can be translated to grains per gallon by multiplying the reading
by the factor 0.0585.
Read the LaMotte Direct Reading Titrator Manual before prceeding.
