DROP TEST SALT WATER (1 drop = 20, 40, 100, 200, or 800 ppm)

COMPONENTS: 1 x 4078 Pipet, Graduated, 3 mL (0.5 mL div.), plastic 1 x 5091 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-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 = 20 or 40 ppm Sodium Chloride

1. Select sample size. Desired Equivalence Sample Size 1 drop = 20 ppm 20.5 mL sample 1 drop = 40 ppm 10 mL sample
2. Rinse and fill 25 mL sample tube (#9198O) to desired mark (Step 1) with water to be tested.
3. Add 1 drop 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 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 red is the endpoint.
5. Multiply drops of R-0706 Silver Nitrate Reagent by desired equivalence factor (Step 1). Record as parts per million (ppm) salt as sodium chloride.

For 1 drop = 100, 200, or 800 ppm Sodium Chloride

1. Select sample size. Desired Equivalence Sample Size

1 drop = 100 ppm 4 mL sample (2 x 2 mL)
1 drop = 200 ppm 2 mL sample 1 drop = 800 ppm 0.5 mL

2. Using a 3 mL pipet (#4078), add desired sample size (Step 1) to 25 mL sample tube (#9198O). Dilute to 10 mL mark with distilled, deionized, or tap water.
3. Add 1 drop 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 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 red is the endpoint.
5. Multiply drops of R-0706 Silver Nitrate Reagent by desired equivalence factor (Step 1). Record as parts per million (ppm) salt as sodium chloride.
