Properties of sodium metabisulfite
  Sodium metabisulfite is a colorless or white crystal with the chemical formula Na2S2O5. It has good reducing properties and is relatively soluble in water. The solution of sodium metabisulfite is acidic and has certain corrosiveness. Its main characteristics are as follows:
  1) Reducing property: Sodium metabisulfite is an effective reducing agent that can react with various oxidants to release sulfur dioxide gas.
  2) Stability: Sodium metabisulfite is relatively stable under dry conditions, but it is prone to decomposition in a humid environment, releasing sulfur dioxide.
  3) Solubility: Sodium metabisulfite has a relatively high solubility in water and can be conveniently prepared into a solution when in use.
