Product Description

Discover the Premium Economical Food Preservatives: Sodium Metabisulfite

Sodium Metabisulfite Experience the purity with Sodium Metabisulfite, a pristine white or delicate yellow crystalline powder or small crystal, exuding a robust SO2 aroma. It boasts a specific gravity of 1.4 and is eagerly soluble in water, rendering its aqueous solution distinctively acidic. On encountering a potent acid, it liberates SO2 to synthesize the corresponding salt. However, exposure to air leads to its oxidation, given its composition as Na2S2O5, making prolonged storage inadvisable. At temperatures exceeding 150 degrees Celsius, it decomposes, releasing SO2.
