Natriumbiszulfitet

Natriumbiszulfitet, also known as sodium bisulfite, has the chemical formula NaHSO3. It is a chemical compound that appears as a white crystalline powder. In solution, it is acidic. Natriumbiszulfitet is commonly used as a reducing agent and a disinfectant. Its properties make it valuable in various industrial applications.

One of the primary uses of natriumbiszulfitet is in the food industry as a preservative and antioxidant. It helps prevent the browning of fruits and vegetables and inhibits the growth of microorganisms. This is why it is sometimes listed as an ingredient in dried fruits, wines, and some processed foods. It can also be used as a bleaching agent in the pulp and paper industry, helping to whiten paper products.

In water treatment, natriumbiszulfitet is employed to remove excess chlorine. It reacts with chlorine to form sodium bisulfate and sodium chloride, thereby neutralizing the disinfectant. Additionally, it finds use in photography as a component of developing solutions. In some chemical processes, it acts as a source of sulfur dioxide. It is important to handle natriumbiszulfitet with care, as it can cause irritation to the skin, eyes, and respiratory tract.
