Description:
Sulfur dioxide, with the chemical formula SO2, is the simplest and most common sulfur oxide. It is a colorless, transparent gas with a pungent odor at room temperature and pressure. It is easily soluble in water, ethanol, and ether. It dissolves in water to form dibasic medium-strong acid sulfurous acid (H2SO3) with bleaching properties. It can form colorless compounds when combined with organic pigments.

Typical Application:
Food Industry ‌
Sulfur dioxide is a food preservative that sterilizes, prevents oxidation, and extends shelf life, notably in winemaking to protect against bacteria and maintain acidity.
‌Chemical Industry
Sulfur dioxide is used in fertilizers, pigments, rubber, plastics, and sulfuric acid production, essential for various industrial applications.
‌Pharmaceutical Industry ‌
Sulfur dioxide serves as a reducing agent, disinfectant, and acidifier in pharmaceuticals, aiding synthesis and preventing bacterial contamination.
In Float Glass Production ‌
Sulfur dioxide in glass manufacturing regulates furnace atmosphere, aids desulfurization, coloring, and treats waste gases.
‌Other Applications‌
Sulfur dioxide serves as a bleaching agent in food and pulp industries, a refrigerant due to easy liquefaction, and an inert solvent.
