  • How is sodium metabisulfite prepared?
  • Sodium metabisulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. When conducted in warm water, Na 2 SO 3 initially precipitates as a yellow solid. With more SO 2, the solid dissolves to give the disulfite, which crystallises upon cooling. which yields a residue of colourless solid Na 2 S 2 O 5.
  • What is disodium metabisulfite used for?
  • The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative agent. When dissolved in water it forms sodium bisulfite.
  • What are the uses of potassium metabisulfite?
  • The uses of potassium metabisulfite are similar to those of sodium metabisulfite; it is used especially in the processing and preserving of foods and beverages ( Sax & Lewis, 1987 ). 1.3. Occurrence 1.3.1. Air
