Description：
Sodium Bisulfite is a white monoclinic crystalline powder with sulfur dioxide odor; relative density: 1.49; very easily soluble in water; can be decomposed when heated; slightly soluble in ethanol;aqueous solution is acidic; have strong reducing property; can be oxidized in the air or loose sulfur dioxide.
Applications：
1.Sodium bisulfite is a common reducing agent in the chemical industries.
2. It is usually added to large piping systems to prevent oxidative corrosion.
3. In biochemical engineering applications, it is helpful to maintain anaerobic conditions within a reactor.
4. In wastewater treatment, sodium bisulfite is often added following disinfection with a chlorine solution to neutralize the residual chlorine before discharging the treated effluent.
