Sodium Bisulfate

Sodium Bisulfite(sodium Hydrogen Sulfite) Is A Chemical Compound With The Chemical Formula NaHSO3. This Salt Of Bisulfite Can Be Prepared By Bubbling Sulfur Dioxide In A Solution Of Sodium Carbonate In Water. Sodium Bisulfite In Contact With Chlorine Bleach Will Release Harmful Fumes. Sodium Bisulfite Is A Common Reducing Agent In The Chemical Industries. As It Readily Reacts With Dissolved Oxygen: 2 NaHSO3 + O2 → 2 NaHSO4 It Is Usually Added To Large Piping Systems To Prevent Oxidative Corrosion. In Biochemical Engineering Applications, It Is Helpful To Maintain Anaerobic Conditions Within A Reactor. Sodium Bisulfite Should Not Be Confused With Sodium Bisulfate Which Is Used As A PH Lowering Chemical For Swimming Pools. In Wastewater Treatment, Sodium Bisufite Is Often Added Following Disinfection With A Chlorine Solution To Neutralize The Residual Chlorine Before Discharging The Treated Effluent.
