Full introduction of sodium hydrosulfite
Sodium hydrosulfite, also known as sodium dithionite, is a chemical compound with the formula Na2S2O4. This material is used as a strong regenerating agent in various industries. In this article, the structure, uses, safety and alternatives of this material are discussed.
Sodium hydrosulfite was discovered in the 19th century by German chemists. This substance is produced from the combination of sodium sulfite and sulfur dioxide and today it is produced industrially on a large scale.
Structure and chemical properties of sodium hydrosulfite
The chemical structure of sodium hydrosulfite with the chemical formula Na2S2O4 includes two sodium ions (Na), two sulfur atoms (S) and four oxygen atoms (O).
The physical properties of this substance are white or light yellow powder and very soluble in water. It is stable at normal temperature and pressure, but decomposes at high temperatures or in the presence of moisture.Applications of sodium hydrosulfite
