DROP TEST CHLORIDE (1 drop = 2 ppm)

COMPONENTS: 1 x 5025 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-C Phenolphthalein Indicator (orange cap), 2 oz, DB 1 x R-0686O-C Sulfuric Acid N (orange cap), 2 oz, DB 1 x R-0807-C Silver Nitrate Reagent, 2 oz, DB.

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.

NOTE: For results in grains per gallon (gpg), fill to 14.6 mL mark.

2. Add 2 drops R-0638O Phenolphthalein Indicator. Swirl to mix. If sample is colorless--proceed to Step 3. If pink, add R-0686O Sulfuric Acid N dropwise, swirling after each drop, until color changes from pink to colorless.

3. Add 5 drops R-0630 Chromate Indicator. Swirl to mix. Sample should turn yellow.

4. Add R-0807 Silver Nitrate Reagent dropwise, swirling and counting after each drop, until color changes from yellow to a milky salmon (brick) red. Always hold bottle in vertical position.

NOTE: Do not add enough R-0807 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-0807 Silver Nitrate Reagent by 2. Record as parts per million (ppm) chloride. For 14.6 mL sample, multiply drops by 0.2. Record as grains per gallon (gpg) chloride.
