IDENTIFICATION A. Identification Tests-General, Potassium B. Identification Tests-General, Phosphate Insoluble Substances: Sample solution: Dissolve 10 g in 100 mL of hot water. Analysis: Filter the Sample solution through a tared filtering crucible, wash the insoluble residue with hot water, and dry at 105C for 2 h. Acceptance criteria: The weight of the residue is NMT 20 mg (NMT 0.2%). Carbonate: Sample: 1 g Analysis: Add 3 mL of water and 2 mL of 3 N hydrochloric acid to the Sample. Acceptance criteria: NMT a few bubbles are evolved. Chloride and Sulfate, Chloride: Sample: 1.0 g Acceptance criteria: Shows no more chloride than corresponds to 0.40 mL of 0.020 N hydrochloric acid (NMT 0.03%) Chloride and Sulfate, Sulfate: Sample: 0.20 g Acceptance criteria: Shows no more sulfate than corresponds to 0.20 mL of 0.020 N sulfuric acid (NMT 0.1%) Arsenic: NMT 3 ppm Iron: Sample solution: Dissolve 0.33 g in 10 mL of water. Analysis: To the Sample solution add 6 mL of hydroxylamine hydrochloride solution (1 in 10) and 4 mL of orthophenanthroline solution prepared by dissolving 1 g of orthophenanthroline in 1000 mL of water containing 1 mL of 3 N hydrochloric acid, and dilute with water to 25 mL. Acceptance criteria: Any red color produced within 1 h is not darker than that of a control prepared from 1 mL of Standard Iron Solution: NMT 30 ppm. Sodium: A solution (1 in 10) tested on a platinum wire imparts no pronounced yellow color to a nonluminous flame. Limit of Fluoride: To pass the test. Acceptance criteria: NMT 0.001% Limit of Monobasic or Tribasic Salt: Sample solution: Dissolve 3 g in 30 mL of water, and cool to 20C. Analysis: Add 3 drops of thymol blue to the Sample solution. Acceptance criteria: A blue color is produced, which is changed to yellow (with a greenish tinge) by the addition of NMT 0.4 mL of 1 N hydrochloric acid. pH: 8.5-9.6, in a solution (1 in 20) Loss on Drying: Dry a sample at 105C to constant weight: it loses NMT 1.0% of its weight. Packaging and Storage: Preserve in well-closed containers. Specifications of Dipotassium Hydrogen Phosphate BP Ph Eur Grade Dipotassium Phosphate BP Ph Eur K2HPO4 -- 174.2 -- CAS 7758-11-4 Dibasic Potassium Phosphate Potassium Phosphate Dibasic DEFINITION Dipotassium phosphate contains not less than 98.0 per cent and not more than the equivalent of 101.0 per cent of K2HPO4, calculated with reference to the dried substance. CHARACTERS A white powder or colourless crystals, very hygroscopic, very soluble in water, very slightly soluble in alcohol. IDENTIFICATION A. Solution S (see Tests) is slightly alkaline B. Solution S gives reaction of phosphates. C. Solution S gives reaction of potassium. TESTS Solution S: Dissolve 5.0 g in distilled water and dilute to 50 ml with the same solvent. Appearance of solution: Solution S is clear and colourless. Reducing substances: Heat on a water-bath for 5 min a mixture of 5 ml of solution S, 5 ml of dilute sulphuric acid and 0.25 ml of 0.02 M potassium permanganate. The solution remains faintly pink. Chlorides: To 2.5 ml of solution S add 10 ml of dilute nitric acid and dilute to 15 ml with water. The solution complies with the limit test for chlorides (200 ppm). Sulphates: To 1.5 ml of solution S add 2 ml of dilute hydrochloric acid and dilute to 15 ml with distilled water. The solution complies with the limit test for sulphates (0.1 per cent). Arsenic: 5 ml of solution S complies with limit test A for arsenic (2 ppm). Iron: 10 ml of solution S complies with the limit test for iron (10 ppm). Heavy metals: Dissolve 2.0 g in 8 ml of water. Acidify with about 6 ml of dilute hydrochloric acid (pH 3 to 4) and dilute to 20 ml with water. 12 ml of the solution complies with limit test A for heavy metals (10 ppm).
