DROP TEST HARDNESS - TOTAL

COMPONENTS: 1 x 5067B Instruction 1 x 9198B Sample Tube, Graduated, 25 mL, plastic w/cap and blue dot 1 x R-0619B-C Hardness Buffer (blue cap), 2 oz, DB 1 x R-0620B-I Hardness Indicator Powder (blue cap), 10 g 1 x R-0683-C Hardness Reagent, 2 oz, DB.

Hardness-total (Drop Test)

1. Rinse and fill 25 mL sample tube (#9198B) to 25 mL mark with water to be tested.
2. Add 5 drops R-0619B Hardness Buffer. Swirl to mix.
3. Add 1 dipper R-0620B Hardness Indicator Powder. Swirl until dissolved. If hardness is present, sample will turn red.
4. Add R-0683 Hardness Reagent dropwise, swirling and counting after each drop, until color changes from red to blue. Always hold bottle in vertical position.
5. Multiply drops of R-0683 Hardness Reagent by 10. Record as parts per million (ppm) total hardness as calcium carbonate.

DROP TEST ALKALINITY - PM/PT

COMPONENTS: 1 x 5067G Instruction 1 x 9198G Sample Tube, Graduated, 25 mL, plastic w/cap and green dot 1 x R-0637-C Methyl Orange Indicator, 2 oz, DB 1 x R-0638G-A Phenolphthalein Indicator (green cap), .75 oz, DB 1 x R-0645-C Total Alkalinity Indicator, 2 oz, DB 1 x R-0687G-C Sulfuric Acid .12N (green cap), 2 oz, DB.

Alkalinity-P/M (Drop Test)

1. Rinse and fill 25 mL sample tube (#9198G) to 25 mL mark with water to be tested.
2. Add 3 drops R-0638G Phenolphthalein Indicator. Swirl to mix. Sample will turn pink if P alkalinity is present--proceed to Step 3. If no pink color, go to Step 4.
3. If pink, add R-0687G Sulfuric Acid .12N dropwise, swirling and counting after each drop, until color changes from pink to colorless. Record drops as P reading. Always hold bottle in vertical position.
4. Add 5 drops R-0637 Methyl Orange Indicator. Swirl to mix. Sample should turn yellow.
5. Continue adding R-0687G Sulfuric Acid .12N dropwise, swirling and counting after each drop, until color just changes from yellow to orange (salmon pink). Record total drops (Steps 3 and 5) as M reading. Always hold bottle in vertical position. 6. Multiply P reading by 10. Record as parts per million (ppm) P alkalinity as calcium carbonate. Multiply M reading by 10. Record as ppm M alkalinity as calcium carbonate.

Alkalinity-P/T (Drop Test)

1. Rinse and fill 25 mL sample tube (#9198G) to 25 mL mark with water to be tested.
2. Add 3 drops R-0638G Phenolphthalein Indicator. Swirl to mix. Sample will turn pink if P alkalinity is present--proceed to Step 3. If no pink color, go to Step 4.
3. If pink, add R-0687G Sulfuric Acid .12N dropwise, swirling and counting after each drop, until color just changes from pink to colorless. Record drops as P reading. Always hold bottle in vertical position.
4. Add 5 drops R-0645 Total Alkalinity Indicator. Swirl to mix. Sample should turn green.
5. Continue adding R-0687G Sulfuric Acid .12N dropwise, swirling and counting after each drop, until color changes from green to red. Record total drops (Steps 3 and 5) as T reading. Always hold bottle in vertical position. 6. Multiply P reading by 10. Record as parts per million (ppm) P alkalinity as calcium carbonate. Multiply T reading by 10. Record as ppm T alkalinity as calcium carbonate.


DROP TEST SULFITE, SODIUM

COMPONENTS: Sulfite, Sodium 1 x 5067W Instruction 1 x 9198W Sample Tube, Graduated, 25 mL, plastic w/cap and white dot 1 x R-0638W-C Phenolphthalein Indicator (white cap), 2 oz, DB 1 x R-0699-C Iodide Iodate Reagent, 2 oz, DB 1 x R-0725-I Acid Starch Indicator Powder, 10 g Sulfite, Sodium (Drop Test)

1. Collect water to be tested in a clean, preferably large-mouthed, bottle to overflowing. Immediately cap and cool to room temperature.
2. Rinse and fill 25 mL sample tube (#9198W) to 25 mL mark with cooled (room temperature) water to be tested.
3. Add 1 drop R-0638W Phenolphthalein Indicator. Swirl to mix. Sample should turn red.
4. Add R-0725 Acid Starch Indicator Powder, a dipper at a time, swirling after each dipper, until color changes from red to colorless. Add 2 more dippers. Swirl until dissolved.
5. Add R-0699 Iodide Iodate Reagent dropwise, swirling and counting after each drop, until color changes from colorless to a faint but permanent blue. Always hold bottle in vertical position.
6. Multiply drops of R-0699 Iodide Iodate Reagent by 10. Record as parts per million (ppm) sodium sulfite.


COLOR CARD TEST LONG RANGE pH (3-11)

1. Rinse and fill 5 mL test cell (#9017) to 5 mL mark with water to be tested.
2. Add 5 drops R-1003U Long Range Indicator. Cap and mix.
3. Lay test cell flat along white area of Color Card (#5425). Match color in test cell with a color standard. Record as pH units.
