*WARNING: Reagents marked with an * are considered to be potential

health hazards. To view or print a Material Safety Data Sheet (MSDS) for

these reagents go to www.lamotte.com. To obtain a printed copy, contact

To order a complete set of refill reagents, order as R-3467. To order individual

reagents or test kit components, use the specified code number.

NOTE: Carefully read the instruction manual for the LaMotte Direct

Reading Titrator before performing the titration described below. The

Titrator is calibrated in terms of alkalinity expressed as parts per million

(ppm) calcium carbonate (CaCO

). Each minor division on the Titrator

scale equals 4 ppm CaCO

EPA AC CEPTED PRO CE DURE

To qualify as an EPA accepted test and to achieve greatest accuracy, the

normality of the *Alkalinity Reagent B should be checked periodically.

Standardize *Alkalinity Reagent B by titrating against 0.05N Na

;

1 mL = 1.00 mg CaCO

. Should a variance of greater than 0.3 mL of

*Alkalinity Reagent B occur, discard and order a fresh bottle of

*Alkalinity Reagent B (Code 4493DR-H). A CaCO

equivalent

standard of 100 ppm is also available (Code 6199-H). Refer to Standard

Methods, 16th edition, 403, 1985.

PHENOLPHTHALEIN (P) ALKALINITY PROCEDURE 1. Fill test tube (0778) to 5 mL line with sample water. 2 Add two drops of *Alkalinity Indicator # 1 (3870). Cap and mix. If a red color develops, P alkalinity is present. Proceed to Steps 3-5. If no red color develops, P alkalinity is not present. Proceed to Step 3 and then skip to Total Alkalinity Procedure Steps 6-9. 3. Fill Direct Reading Titrator with *Alkalinity Reagent B (4493). Insert Titrator in center hole of test tube cap. 4.

CALCULATION OF ALKALINITY RELATIONSHIPS Results obtained from Phenolphthalein and Total Alkalinity determinations offer a means for the stoichiometric classification of three principal forms of Alkalinity present in many water supplies. Classification attributes the entire alkalinity to bicarbonate, silica, phosphoric and boric acids. This classification system further assumes incompatilibity of Hydroxide and Bicarbonate Alkalinities in the same sample.
