SODIUM DITHIONATE DIHYDRATE

Description:
Sodium dithionite dihydrate, with the CAS number 10101-85-6, is an inorganic compound characterized by its white crystalline appearance. It is a sodium salt of dithionic acid and is commonly used as a reducing agent in various chemical processes, including dyeing and bleaching in the textile industry. The dihydrate form indicates that it contains two molecules of water for each molecule of sodium dithionite, which contributes to its stability and solubility in water. Sodium dithionite is known for its strong reducing properties, making it effective in reducing metal ions and other compounds. It is also utilized in organic synthesis and as a preservative in some food products. However, it must be handled with care, as it can release toxic gases, such as sulfur dioxide, upon decomposition. Additionally, it is important to store sodium dithionite dihydrate in a cool, dry place to prevent degradation and maintain its efficacy as a reducing agent.
