Physical and chemical properties:
White crystalline or powder form; triangular prism crystal shape; alkaline water solution with pH at 9 – 9.5; The highest water solubility is about 28% with temperature at 33.4°C. When exposed to air, it is oxidized to form sodium sulfate. When heated to high temperature, it decomposes to form sodium sulfide; Density: 2.633(15.4°C), Refractive Index: 1.565; Molecular Weight: 126.04.

Application:
It is used in dyeing industry as deoxidizer and bleaching agent for a variety of cotton fabric treating and scouring, which can prevent fabrics from local oxidation and deterioration of fibre strength. In photographic industry it is used as a reagent. In organic industry it is used as reducing agent in production of m-phenylenediamine, 25 - bared oxazolone, amino salicylic acid, etc. Textile industry uses it as a stabilizer for synthetic fibre. Other applications include various uses in paper mills, electronic industry, water treatment, etc.

Nature:
White crystal or powder; no foul. Soluble in water, very slightly soluble in ethanol, almost insoluble in ether. White hexagonal prismatic crystals, soluble in water (0 ℃ 12.54g/100ml water; 80 ℃ when the 283g/100ml water), in 33.4 ℃ The maximum solubility of about 28% when the aqueous solution is alkaline, PH value is about 9 ~ 9.5 . Slightly soluble in alcohol, insoluble in liquid chlorine, ammonia. Easily oxidized in air sodium, when the temperature is decomposed into sodium sulfide. To strengthen the reducing agent, reacts with sulfur dioxide, sodium bisulfite, reacted with the acid salt.
