POTASSIUM SULFITE Chemical compatibility with O-rings, rubbers, & plastics

Potassium Sulfite (K2SO3) is an inorganic compound that appears as a white crystalline powder or granules. It is highly soluble in water, forming a solution with a slightly sulfurous odor. This compound is widely used as a preservative and antioxidant in the food and beverage industry, particularly in winemaking and the preservation of dried fruits and vegetables. Potassium Sulfite helps to prevent the growth of unwanted microorganisms and oxidation of products, thereby extending their shelf life. In the chemical industry, it serves as a reducing agent and in the preparation of other sulfur-containing compounds. Additionally, it finds applications in the photographic industry as a component of developers and fixers. In environmental chemistry, Potassium Sulfite is used in air and water treatment processes to remove excess chlorine and other contaminants.
