DROP TEST CHLORIDE (1 drop = 10, 25, 50, 100, or 500 ppm)

COMPONENTS: 1 x 4078 Pipet, Graduated, 3 mL (0.5 mL div.), plastic 1 x 5006 Instruction 2 x 9198O Sample Tubes, Graduated, 25 mL, plastic w/cap and orange dot 1 x R-0630-C Chromate Indicator, 2 oz, DB 1 x R-0706-C Silver Nitrate Reagent, 2 oz, DB.

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.

For 1 drop = 10 or 25 ppm or 1 gpg

1. Select sample size for required equivalence. Required Equivalence Sample Size 1 drop = 10 ppm Cl- 25 mL 1 drop = 1 gpg Cl- 14.6 mL 1 drop = 25 ppm Cl- 10 mL
2. Rinse and fill 25 mL sample tube (#9198O) with required sample size with water to be tested.
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 a 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 required equivalence factor. Record as parts per million (ppm) or grains per gallon (gpg) chloride. NOTE: For results as sodium chloride, multiply final value by 1.65.

For 1 drop = 50, 100, or 500 ppm

1. Select sample size for required equivalence. Required Equivalence Sample Size
1 drop = 50 ppm Cl- 5 mL (2 x 2.5 mL)
1 drop = 100 ppm Cl- 2.5 mL
1 drop = 500 ppm Cl- 0.5 mL

2. Using a 3 mL pipet (#4078) add required sample size to 25 mL sample tube (#9198O). Dilute to 10 mL mark with distilled, deionized, or chloride-free water.
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 a 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 required equivalence factor. Record as parts per million (ppm) chloride.

NOTE: For results as sodium chloride, multiply final value by 1.65.
