Sodium Bisulfite

Sodium bisulfite (NaHSO3) is a white, crystalline powder or granular substance that is highly soluble in water. It is a sulfite compound commonly used in various industries, including water treatment and food processing. Sodium bisulfite acts as a reducing agent, capable of removing or neutralizing excess chlorine in water. It is frequently used as a dechlorination agent in water treatment to eliminate chlorine residual after disinfection processes. Additionally, sodium bisulfite has antioxidant properties, helping to prevent oxidation and the degradation of certain chemicals. In food processing, it serves as a preservative, preventing spoilage and maintaining the quality of food products. Its general characteristics are:

  • Chemical Formula: NaHSO3
  • Physical State: White crystalline powder or granules
  • Solubility: Highly soluble in water
  • Taste: Slightly acidic taste
  • pH: Acidic substance with a pH below 7 in solution
  • Density: Approximately 1.48 g/cm³
  • Melting Point: Decomposes above 150 °C (302 °F)
  • Odor: Sulfurous odor
