Product Description
Sodium Bisulphite (NaHSO₃), also known as Sodium Hydrogen Sulfite, is a white crystalline or granular powder with a characteristic sulfurous odor. It is a reducing agent commonly used in analytical chemistry, food preservation, and industrial processes.
Sodium Bisulphite is produced by bubbling sulfur dioxide through a sodium carbonate or sodium hydroxide solution. It is widely employed for chemical reduction, dechlorination, and preservation due to its ability to release sulfur dioxide (SO₂) in aqueous solutions. In laboratories, it is frequently used in quantitative analysis and organic synthesis as a mild reducing agent.
