Sodium Thiosulfate USP Grade Specifications: Na2S2O3-5H2O --- 248.18 Na2S2O3 --- 158.11 Thiosulfuric acid, disodium salt, pentahydrate; Disodium thiosulfate pentahydrate CAS 10102-17-7 Anhydrous CAS 7772-98-7. DEFINITION Sodium Thiosulfate contains NLT 99.0% and NMT 100.5% of sodium thiosulfate (Na2S2O3), calculated on the anhydrous basis. IDENTIFICATION A. Infrared Absorption B. Identification Tests: General, Sodium Calcium: Sample solution: Dissolve 1 g in 20 mL of water. Analysis: To the Sample solution add a few mL of ammonium oxalate. Acceptance criteria: No turbidity is produced. Water Determination: Sample: 1.0 g Analysis: Dry the Sample under vacuum at 40C to 45C for 16 h. Acceptance criteria: 32.0% to 37.0% Sodium Thiosulphate BP Ph Eur Grade Specifications Na2S2O3-5H2O DEFINITION Content: 99.0 per cent to 101.0 per cent of Na2S2O3-5H2O. CHARACTERS Appearance: Transparent, colorless crystals, efflorescent in dry air. Solubility: Very soluble in water, practically insoluble in ethanol 96 per cent. It dissolves in its water of crystallization at about 49C. IDENTIFICATION A. It decolorizes iodinated potassium iodide solution. B. To 0.5 ml of solution S (see Tests) add 0.5 ml of water R and 2 ml of silver nitrate solution. A white precipitate is formed which rapidly becomes yellowish and then black. C. To 2.5 ml of solution S add 2.5 ml of water and 1 ml of hydrochloric acid. A precipitate of sulphur is formed and gas is evolved which gives a blue colour to starch iodate paper. D. 1 ml of solution S gives reaction of sodium. TESTS Solution S: Dissolve 10.0 g in carbon dioxide-free water R prepared from distilled water R and dilute to 100 ml with the same solvent. Appearance of solution: The freshly prepared solution is clear and colourless. Dissolve 10.0 g in 50 ml of distilled water, add 1 ml of 0.1 M sodium hydroxide and dilute to 100 ml with the same solvent. pH: 6.0 to 8.4 for the freshly prepared solution S. Sulphates and sulphites Maximum 0.2 per cent. Sulphides To 10 ml of solution S add 0.05 ml of a freshly prepared 50 g/l solution of sodium nitroprusside. The solution does not become violet. Heavy metals Maximum 10 ppm. Sodium Thiosulfate FCC Food Grade Specifications Sodium Hyposulfite Na2S2O3-5H2O Formula wt 248.19 DESCRIPTION Sodium Thiosulfate or Sodium Thiosulphate occurs as large, colorless crystals or as a coarse, crystalline powder.
