Sodium dithionite (C09-1046-992)

Product introduction:It has a slight special smell. Sensitive to light. There are anhydrous and dihydrate crystalline forms in the solid state. The dihydrate crystal is unstable and can be dehydrated when it is gradually heated to a certain temperature in alkaline medium, and it can be transformed into anhydrous crystal, which is easy to decompose. Generally, it is more stable in alkaline medium than in neutral medium, and it is more stable when dry than when wet. Moisture, heat or exposure to air can accelerate its decomposition and even combustion. During decomposition, sulfur dioxide and a large amount of heat are released, and it can spontaneously ignite at 250 ℃. In the presence of moisture or in aqueous solution, sodium bisulfite and sodium bisulfite are quickly formed and are acidic. It is easily soluble in water and slightly soluble in ethanol. The aqueous solution is neutral. It is easy to burn when wet. Due to its unstable nature, a certain amount of stabilizer is added to the finished product. Specifications and Purity: 59%.
