DEFINITION
Content: 98.0 per cent to 102.0 per cent.
CHARACTERS
Appearance: Crystalline mass or orange-yellow or brownish-yellow crystals, very hygroscopic.
Solubility: Very soluble in water and in ethanol (96 per cent), freely soluble in glycerol.

B. It gives reaction of iron.
TESTS
Solution S: Dissolve 10 g in distilled water and dilute to 100 ml with the same solvent.
Acidity: In a suitable polyethylene container, dissolve 3.0 g of potassium fluoride in 15 ml of water. Titrate with 0.1 M sodium hydroxide using 0.1 ml of phph solution as indicator until a pink colour is obtained. Add 10 ml of solution S and allow to stand for 3 h. Filter and use 12.5 ml of the filtrate. Not more than 0.30 ml of 0.1 M sodium hydroxide is required to change the colour of the indicator to pink.
Free chlorine: Heat 5 ml of solution S. The vapour does not turn starch iodide paper blue.
Sulphates: Maximum 100 ppm.
Ferrous ions: Maximum 50 ppm.
Heavy metals: Maximum 50 ppm.
