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 does not turn red, P Alkalinity is 0. If solution turns red, proceed to Step 3.

3. Fill the Direct Reading Titrator (0382) with *Alkalinity Titration Reagent B

(4493DR). Insert Titrator into center hole of test tube cap.

4. While gently swirling tube, slowly press plunger to titrate until red color disap-

pears. Read the test result directly from the scale where the large ring on the Titra-
tor meets the Titrator barrel. Record as ppm P Alkalinity as CaCO

3

.

EXAMPLE: Plunger tip is 3 minor divisions below line 80. The test result is 80
plus 12 (3 divisions x 4) equals 92 ppm.

5. If plunger tip reaches the bottom line on the Titrator scale (200 ppm) before the

color change occurs, refi ll the Titrator and continue the titration. When recording
test result, be sure to include the value of original amount of reagent dispensed
(200 ppm).
NOTE: Do not move Titrator plunger after the P Alkalinity endpoint has been
obtained. The titration is continued in the T Alkalinity procedure.

TOTAL (T) ALKALINITY PROCEDURE

6. Being careful not to move plunger, remove Titrator and cap from test tube con-

taining sample that was titrated in Step 4.

7. Add one BCG-MR Tablet (T-2311). Cap and shake until tablet disintegrates.

Solution will turn green-blue.
