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 CHLORIDE

COMPONENTS: 1 x 5067O Instruction 1 x 9198O Sample Tube, Graduated, 25 mL, plastic w/cap and orange dot 1 x R-0630-C Chromate Indicator, 2 oz, DB 1 x R-0638O-A Phenolphthalein Indicator (orange cap), .75 oz, DB 1 x R-0687O-C Sulfuric Acid .12N, (orange cap), 2 oz, DB 1 x R-0706-C Silver Nitrate Reagent, 2 oz, DB.

Chloride (Drop Test)

NOTE: When sulfite content of sample water to be tested exceeds 10 ppm, the sulfite should be oxidized to prevent interference in test. A 25 mL water sample is first adjusted to the appropriate pH, then 1 mL (or 24 drops) of R-0649 3% Hydrogen Peroxide Solution (sold separately) is added and thoroughly mixed. Continue with the rest of the procedure.

1. Rinse and fill 25 mL sample tube (#9198O) to 25 mL mark with water to be tested.
2. Add 2 drops R-0638O Phenolphthalein Indicator. Swirl to mix. If sample turns red, add R-0687O Sulfuric Acid .12N dropwise, swirling after each drop, until color changes from red to colorless.
3. Add 5 drops R-0630 Chromate Indicator. Swirl to mix. Sample should turn yellow.
4. Add R-0706 Silver Nitrate Reagent dropwise, swirling and counting after each drop, until color changes from yellow to milky salmon (brick) red. Always hold bottle in vertical position.

NOTE: Do not add enough R-0706 Silver Nitrate Reagent to give a brown color. First change from yellow to a milky salmon (brick) red is the endpoint. 5. Multiply drops of R-0706 Silver Nitrate Reagent by 10. Record as parts per million (ppm) chloride.
