1. Fill the graduated cylinder (0418) to the 50 mL line with sample water. Transfer to a 125 mL Erlenmeyer flask (0431).
2. Add one Phenolphthalein Tablet (T-2246). If the solution turns red, P Alkalinity is present; proceed to Step 3. If the solution is colorless, P Alkalinity is zero; proceed to Step 4.
3. Fill buret (0427) with *Alkalinity Titration Reagent (4015). While swirling flask, slowly add *Alkalinity Titration Reagent until red color disappears. Record buret reading as Value P. Do not refill buret if determining T Alkalinity.
NOTE: If chlorine levels greater than 2 ppm are present, the chlorine should be neutralized before testing for T Alkalinity. Use a dechlorinating agent, such as 1 drop of 0.1N Sodium Thiosulfate (6155).
4. To the same flask add one BCG-MR Indicator Tablet (T-2311). Solution will turn greenish-blue.
5. While gently swirling flask, titrate sample with *Alkalinity Titration Reagent until greenish-blue color changes to pink. Record buret reading as Value T.
6. Multiply Value P by 20. Record as ppm P Alkalinity as CaCO3.
Value P x 20 = P Alkalinity as ppm CaCO
3
7. Multiply Value T by 20. Record as ppm T Alkalinity as CaCO3.
Value T x 20 = T Alkalinity as CaCO
3
NOTE: Methyl Orange Indicator (2230) may be used in place of the
BCG-MR Indicator Tablets to run the test for Total Alkalinity. The color change will be from yellow to orange-red at the endpoint.
