Calcium sulfite

Description:
Calcium sulfite, with the chemical formula CaSO₃, is an inorganic compound characterized by its white crystalline solid form. It is primarily used in various industrial applications, including as a reducing agent in the production of sulfur dioxide and in the treatment of flue gases to remove sulfur dioxide emissions. Calcium sulfite is also utilized in the paper industry as a bleaching agent and in the food industry as a preservative. It is slightly soluble in water, and its solubility increases with temperature. The compound can be produced through the reaction of calcium hydroxide with sulfur dioxide, resulting in the formation of calcium sulfite and water. In terms of safety, calcium sulfite is generally considered to have low toxicity, but it can cause irritation to the skin, eyes, and respiratory tract upon exposure. Its stability under normal conditions makes it a useful compound in various chemical processes, although it can decompose upon heating to release sulfur dioxide.

    Calcium sulfite

    CAS:
    <p>Calcium sulfite is a chemical compound that contains calcium, sulfur and oxygen. It is typically used as a food additive, although it can also be used as a treatment for wastewater. Calcium sulfite reacts with hydrogen fluoride to form calcium fluoride and hydrogen sulfide. This reaction is reversible, but only if the pH of the solution is greater than 2. In addition to this reaction, calcium sulfite can react with sodium citrate to form an alkanoic acid and hydrogen sulfate. The reaction mechanism of these reactions has not been fully elucidated, but genotoxic effects have been observed in animals following exposure to high concentrations of calcium sulfite.</p>
