SODIUM THIO SULPHATE (HYPO) INDUSTRIAL GRADE
Sodium Hyposulfite is an inorganic compound with the formula Na2S2O3.xH2O. Typically it is available as the white or colourless pentahydrate, Na2S2O3•5H2O. The solid is an efflorescent (loses water readily) crystalline substance that dissolves well in water. It is also called sodium hyposulfite or “hypo”. Sodium thiosulfate is an inorganic sodium salt composed of sodium and thiosulfate ions in a 2:1 ratio. The melting point of Sodium Hyposulfite is 48.5 °C. It is practically insoluble in alcohol. Sodium Hyposulfite is 20.9 g soluble in 100 cc water. The density of Sodium Hyposulfite is 1.7 g/cm³.
