Sodium Metabisulfite, 98%
Sodium Metabisulfite (Na₂S₂O₅), also known as Sodium Pyrosulfite or Disodium Disulfite, is a high-purity food-grade compound widely used for its preservative, antioxidant, and bleaching properties. When dissolved in water, it forms Sodium Bisulfite (NaHSO₃), which is highly effective in removing free chlorine and reducing hypochlorous acid in water. It is commonly used in water treatment, the food and beverage industry, and as a cost-effective chemical reducing agent compared to alternatives like sulfur dioxide. Sodium Metabisulfite is a biostatic agent, making it ideal for extending the shelf life of various products. Fine crystal in texture, it is toxic by inhalation and must be handled with care, with a tolerance limit of 5 mg per cubic meter of air. This versatile compound offers efficiency and reliability in a variety of industrial, food, and chemical applications.
