  • 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 the chemical formula for sodium metabisulfite?
  • Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) is an inorganic compound of chemical formula Na 2 S 2 O 5. The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative agent.
  • Can sodium metabisulfite be used to remove tree stumps?
  • Concentrated sodium metabisulfite can be used to remove tree stumps. Some brands contain 98% sodium metabisulfite, and cause degradation of lignin in the stumps, facilitating removal. It is also used as an excipient in some tablets, such as paracetamol.
