Chemical Titration

Procedure 3022 WI-1978-11

• 1) Rinse sample test tube. Using the graduated dropper, add 25 ml of the solution to be tested.

• 2) Add 20 drops of R-7061 Sodium Thiosulfate and then add 2 drops of R-0638W Phenolphthalein Indicator. Swirl to mix; sample should turn red.

• 3) Add R-0737 3N Hydrochloric Acid one drop at a time. Swirl to mix after each drop. Count the number of drops until the color changes from red to colorless. Always hold the reagent bottle in a vertical position. Some samples may change from red to pink to colorless. Always continue to the colorless point. This is more easily observed if the test is done against a white background.

• 4) From the number of drops, estimate the concentration of 3022. 1 Drop=1490 PPM

• 5) Rinse the sample

Procedure 81021 WI-19111-58

• 1) Rinse sample test tube. Using the graduated dropper, add 125 ml of the solution to be tested.

• 2) Add (6) drops of R0645 Total Alkalinity Indicator and swirl to mix. Sample should turn green.

• 3) Add R-0724 12N Hydrochloric Acid one drop at a time. Swirl to mix after each drop. Count the number of drops until the color changes from green to pink. Always hold the reagent bottle in a vertical position. Some samples may change from green to brown to pink. Always continue to the pink end point. his is more easily observed if the test is done against a white background.

• 4) From the number of drops, estimate concentration of 81021. 1 Drop=183PPM

Procedure BioSide HS 15% Peracetic Acid test Method

• 1) Using one of the 10ml syringes carefully measure 10 ml (cc) of the sample to be tested.

• 2) Carefully add the contents of the syringe to the test vial.

• 3) To the sample add 5 drops of #1 Reagent and swirl the test vial to mix.

• 4) To the sample add 5 drops of #2 Reagent and swirl the test vial to mix.

• 5) To the sample add 5 drops of #3 Reagent and swirl the test vial to mix. Wait 10 seconds.

• 6) To the sample add 5 drops of #4 Reagent and swirl the test vial to mix. Sample should be blue/black in color.

• 7) Add #5 Reagent, drop by drop while swirling the test vial, counting the drops, until the sample turns COLORLESS and is stable for at LEAST 10 seconds.

• 8) From the number of drops, estimate concentration of BioSide HS 15% 1 Drop=3.5 PPM

Procedure ChemSan 1220

• 1) Fill test tube to the 10 ml line with sample water. Dilute to 15 ml line with QAC-free tap water or distilled water.

• 2) Add 5 drops of QAC Indicator Solution (6413). Cap and mix. Solution will turn green.

• 3) Fill Direct Reading Titrator(0383) with QAC Titration Solution (6412). Insert titrator tip into the center of the hole of the test tube cap.

• 4) While gently swirling the tube, slowly press the plunger to titrate until the green tint just disappears and the solution turns brown.

• 5) Read test results where large ring on Titrator meets titrator scale. Record as PPM QAC.

• 6) From the number of drops, estimate concentration of ChemSan 1220. Titrator syringe division= 10PPM.
