LaMotte P, T and OH Alkalinity Drop Count Test Kit – 7515

3467-sContents:

  • 100 Phenolphthalein Tablets
  • 100 BCG-MR Indicator Tablets
  • 30 mL *Barium Chloride Solution, 10%
  • 2 x 60 mL *Alkalinity Titration Reagent
  • 1 Test Tube, 5-10-15 mL, glass, w/cap
  • 1 Pipet, plain, plastic
  • 1 Acid Demand Index

This kit uses titrations with standard acid to the phenolphthalein (P) and total (T) alkalinity endpoint. Where hydroxyl (OH) alkalinity is determined directly, the sample is penetrated with barium to precipitate carbonates. All results are expressed as CaCO3 and this test kit contains 50 tests to 200ppm.

HYDROXIDE ALKALINITY

1. Fill test tube (0778) to 5 mL line with sample water.
2. Add 10 drops of *Barium Chloride Solution, 10% (6117). A white precipitate will form if carbonates are present.
3. Add one Phenolphthalein Tablet (T-2246). Cap and mix until tablet disintegrates. If solution does not turn red, the Hydroxide Alkalinity is zero. If solution turns red, proceed to Step 4.
4. Fill the pipet (0352) with *Alkalinity Titration Reagent (6102PS). Hold pipet vertically. While gently swirling tube, add *Alkalinity Titration Reagent, one drop at a time, until color changes from red to colorless. Count the number of drops added.
5. Multiply number of drops added in Step 4 by 10. Record as ppm Hydroxide Alkalinity as CaCO3. Number of Drops of Titration Reagent x 10 = ppm Hydroxide Alkalinity expressed as ppm Calcium Carbonate (CaCO3)

PHENOLPHTHALEIN (P) ALKALINITY PROCEDURE:

1. Fill test tube (0778) to 5 mL line with sample water.
2. Add one Phenolphthalein Tablet (T-2246). Cap and mix until tablet disintegrates. If solution turns red proceed to Step 3. If solution does not turn red, P Alkalinity is zero.
3. Fill pipet (0352) with *Alkalinity Titration Reagent (6102PS). Hold pipet vertically. While gently swirling tube, add *Alkalinity Titration Reagent, one drop at a time, until color changes from red to colorless. Count the number of drops added.
4. Multiply the number of drops added in Step 3 by 10. Record as ppm P Alkalinity as CaCO3.

Number of Drops of Titration Reagent x 10 = ppm Phenolphthalein Alkalinity expressed as ppm Calcium Carbonate (CaCO3)

5. Save sample for T Alkalinity test.

TOTAL (T) ALKALINITY PROCEDURE:

1. Use the sample from the P Alkalinity test, or fill the test tube (0778) to the 5 mL line with sample water.
2. Add one BCG-MR Indicator Tablet (T-2311). Cap and mix until tablet disintegrates.
3. Fill the pipet with *Alkalinity Titration Reagent (6102PS). Hold pipet vertically. While gently swirling tube, add *Alkalinity Titration Reagent, one drop at a time, until color changes from green to pink. Count the number of drops added.
4. Multiply number of drops used in Step 3 by 10. Record as ppm T Alkalinity as CaCO3.

NOTE: If the same sample is used for both the P and T Alkalinity tests, add both test results to calculate T Alkalinity.

Number of Drops of Titration Reagent x 10 = Total Alkalinity expressed as ppm Calcium Carbonate (CaCO3)

When testing swimming pool water, consult the Acid Demand Index (1546) to determine if the Total Alkalinity value is excessive. The Index will indicate the recommended quantity of acid required to offset high alkalinity content.
