COMPONENTS: 1 x 5052 Instruction 1 x 6051 Indicator Strips, pH, 2.5-4.5 1 x 9198P Sample Tube, Graduated, 25 mL, plastic w/cap and purple dot 1 x R-0627H-4-C Hydrochloric Acid .25N, 2 oz, DB 1 x R-0697-C Thiosulfate N/10, 2 oz, DB 1 x R-0800-I CAS Indicator Powder, 10 g 1 x R-0803-C Phosphonate Titrating Solution, 2 oz, DB.

NOTE: Positive interferences: Fluoride and iron at all levels; Orthophosphate >5 ppm PO4; Polyphosphate >1 ppm PO4 NOTE: Run a blank with fluoride-free water. Normal blank requires about 2 drops of R-0803 Phosphonate Titrating Solution to reach endpoint.

1. Rinse and fill 25 mL sample tube (#9198P) to 25 mL mark with water to be tested.
2. Add: 1 drop R-0697 Thiosulfate N/10 1 level dipper R-0800 CAS Indicator Powder Swirl to mix.
3. Adjust pH between 3.6 and 3.9: Place 1 indicator strip in sample. Add 1 drop R-0627H-4 Hydrochloric Acid .25N. Swirl sample 15 seconds to mix. Remove indicator strip and match color with printed color standards on indicator strip container. Read printed pH value. If necessary, repeat above procedure using same indicator strip until a pH between 3.6 and 3.9 is obtained. Sample should be peach (pink-orange).
4. Add R-0803 Phosphonate Titrating Solution dropwise, swirling and counting after each drop, until color changes from peach to purple. Always hold bottle in vertical position.
