Name: Industry Grade Price Anhydrous Sodium Sulfite Na2so3
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.

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 s
trength. 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.
