Sodium Metabisulfite (SMBS), with the chemical formula Na₂S₂O₅, is an inorganic compound composed of sodium, sulfur, and oxygen. It appears as a white or creamy powder and is highly soluble in water. Sodium Metabisulfite is primarily used across several industries, including food processing, textile manufacturing, mining, water treatment, and paper production.

In the food industry, Sodium Metabisulfite is used as a preservative and bleaching agent for dried fruits, wine, and vegetables. In textiles, it acts as a bleaching agent and a reducing agent in dyeing processes. The compound also plays a crucial role in water treatment as it is used to neutralize chlorine in water treatment plants. In mining, it is employed to extract precious metals, while in paper production, it aids in the bleaching and pulping of wood fibers.

The versatility of Sodium Metabisulfite in these industries makes it an indispensable chemical. Its ability to prevent oxidation, reduce chlorine, and act as a preservative ensures its demand across various sectors.
