A white sand crystallization or light yellow powder chemicals.
It insoluble in ethanol while soluble in sodium hydroxide solution. With water it will burn and has a strong reaction. The water solution is unstable. It belongs to the strong reducing
agent. When exposed to the air it can absorb oxygen and oxidation, but also easy to absorb moisture and metamorphism. It can seize the oxygen in air to agglomerate and irritating sour.Toxic and it has a stimulating effect to eyes and mucosa.

Molecular formula: Na2S2O4
Appearance: Sodium hydrosulfite is also known as sodium dithionite, and is white crystalline powder or yellowish. It is soluble in sodium hydroxide solution and slightly soluble in ethanol.Powdered anhydrous sodium hydrosulfite with a small amount of water may ignite in air by the heat of decomposition.
