Sulfurous acid, scientifically represented by the chemical formula H2SO3 and identified by CAS number 7782-99-2, is a fascinating inorganic compound primarily known as an aqueous solution of sulfur dioxide in water. While it's a weak and unstable acid in its free state, its solutions play crucial roles across various industries. For businesses seeking reliable chemical raw materials, understanding the properties and sourcing of Sulfurous Acid is paramount. As a prominent manufacturer and supplier based in China, we aim to provide comprehensive insights into this versatile chemical.

Key Properties and Characteristics

Sulfurous acid is characterized by its reducing and disinfectant properties. It is often prepared by dissolving sulfur dioxide gas in water. Although attempts to isolate pure, anhydrous sulfurous acid have proven difficult due to its tendency to revert to sulfur dioxide and water, its aqueous solutions are widely utilized. These solutions are typically colorless and possess a characteristic odor of sulfur dioxide. The compound's instability means it is often handled as a solution, and understanding its reactivity, especially its propensity to be oxidized to sulfuric acid, is key for safe and effective use.

Industrial Applications of Sulfurous Acid

The versatility of Sulfurous Acid, identified by CAS 7782-99-2, makes it a valuable commodity for numerous industrial sectors. One of its primary uses is as a potent reducing agent. In chemical synthesis, it can be employed to reduce metal ions or organic compounds. Furthermore, its disinfectant capabilities are recognized, making it useful in applications where microbial control is essential.

Beyond these core functions, Sulfurous Acid also serves as a mild bleaching agent. Unlike chlorine-based bleaches, it is often preferred for materials that are sensitive to chlorine, such as wool, silk, and certain natural fibers. This makes it an attractive option for textile processing and the treatment of various natural products.
