NOTE: Carefully read the instruction manual for the LaMotte Direct
Reading Titrator before performing the titration as described below. The
titrator is calibrated in terms of Alkalinity expressed as parts per million
(ppm) calcium carbonate (CaCO
3
). Each minor division on the titrator
scale equals 4 ppm CaCO

PRO CE DURE
PHENOLPHTHALEIN (P) ALKALINITY
NOTE: P Alkalinity results are not required for Corrosion Index
Calculations.
1.
Fill titration tube (0778) to 5 mL line with the water sample.
2. Add two drops of *Alkalinity Indicator # 1 (3870) to titration tube.
Cap and mix. If a pink to red color does not develop in solution, P
alkalinity is zero.
3. If a red color develops, P Alkalinity is determined. Fill the Direct
Reading Titrator with Alkalinity Titration Reagent B (4493DR) as
described in instruction manual. Insert titrator in center hole of
titration tube cap
4. Slowly depress plunger and swirl after each drop until RED color
disappears. Read test result directly from the scale where the large ring
on the Titrator meets the Titrator barrel. Express result as P Alkalinity
in ppm CaCO
3
.
EXAMPLE: Plunger tip is 3 minor division below line 80. The test
result is 80 plus 3 division x 4 equals 92 ppm, since each division is
equal to 4 ppm.
