Product Description

Product Description

 

Chemical formula: NA2S2O5
English name: Sodium metabisulfite
Molecular weight: 190.10

Physical and chemical properties
1.Appearance: White or slightly yellow crystalline powder.
2.Odor: There is a strong irritant odor
3.Solubility: Easily soluble in water, its aqueous solution is acidic. The solubility in water increases with temperature, and at 20 ºC, the solubility is about 64g/100mL of water. It is also soluble in glycerol and slightly soluble in ethanol.
4.Density: Approximately 1.48g/cm ³
5.Stability: It is easily oxidized in air, and when exposed to moisture or humid air, it will slowly oxidize and decompose, and generating sodium sulfate. When heated to around 150 ºC, it will decompose and produce products such as sodium sulfate.
