Sodium Metabisulfite 64%

 

Sodium metabisulfite is white or yellow crystalline powder or small crystals, with a strong smell of SO2, the proportion of 1.4, soluble in water, acidic aqueous solution, and acid contact with the release of SO2 and generates the corresponding salts, long home air, the oxidation into Na2S2O4, so the product can not go far. If it higher than 1500C, the decomposition of SO2.

Uses: It used in dyeing and printing industry, organic synthesis, printing, leather, pharmaceutical and other sectors;
