DROP TEST CHLORIDE (1 drop = 2, 10, or 100 ppm)

COMPONENTS: 1 x 4078 Pipet, Graduated, 3 mL (0.5 mL div.), plastic 1 x 5021 Instruction 1 x 9198 Sample Tube, Graduated, 25 mL, plastic w/cap 1 x R-0630 Chromate Indicator, DB 1 x R-0638 Phenolphthalein Indicator, DB 1 x R-0686 Sulfuric Acid N, DB 1 x R-0807 Silver Nitrate Reagent, 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.

1. Select sample size. Desired Equivalence Sample Size

1 drop = 2 ppm 25 mL 1 drop = 10 ppm
5 mL 1 drop = 100 ppm 0.5 mL

2. Using a 3 mL pipet (#4078) or a 25 mL sample tube (#9198), add desired sample size (Step 1) to 25 mL sample tube. If necessary, dilute 0.5 or 5 mL sample to 10 mL mark with distilled, deionized, or chloride-free water.
3. Add 2 drops R-0638 Phenolphthalein Indicator. Swirl to mix. If sample turns red, add R-0686 Sulfuric Acid N dropwise, swirling after each drop, until color changes from red to colorless.
4. Add 5 drops R-0630 Chromate Indicator. Swirl to mix. Sample should turn yellow.
5. 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.

6. Multiply drops of R-0807 Silver Nitrate Reagent by desired equivalence factor (Step 1). Record as parts per million (ppm) chloride.

SLIDE & MIDGET COMPARATOR TEST ORTHOPHOSPHATES & POLYPHOSPHATES

IN GENERAL This method is based on the formation of phosphomolybdic acid which is subsequently reduced with stannous chloride to produce a blue color whose intensity is proportional to the phosphate (PO4) present. Interferences are reduced to a minimum. The presence of 10,000 ppm of silica (SiO2), 100 ppm of ferrous or ferric iron, or 1000 ppm of sulfite causes no error. The water to be tested must be carefully filtered with a good grade of filter paper to free it from sludge and scale. Mere traces of sludge will cause serious errors. If repeated filtration does not clarify the water, add 0.5 grams potassium nitrate crystals to 25 mL of the sample water, heat to boiling, cool, dilute to 25 mL with distilled water, and filter. If the water is very highly colored by tannin or other highly colored organic matter, so that a phosphate determination is difficult or impossible, it can be effectively decolorized with R-0727 Activated Charcoal. Add half a teaspoon of activated charcoal to a pint container of the colored sample water. Close the container and shake sample well. Decolorization should take place in from 5 to 15 minutes. The treated sample is then filtered as instructed above. From this point on follow the procedure outlined in the Orthophosphate or Polyphosphate tests.
