Physical Character

sodium thiosulfate pentahydrate

White or yellowish crystalline powder. Relative density 1.4, soluble in water (20 ℃ for 54 g / 100 ml of water;At 100 ℃ for 81.7 g / 100 ml water) acidic aqueous solution, soluble in glycerin, slightly soluble in alcohol. Easy decomposition when being affected with damp, easy oxidation into sodium sulfate in air and contact with strong acid release sulfur dioxide and generate the corresponding salts, heated to 150 ℃.
