The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used. Sulfites are substances that naturally occur in some foods and the human body. They are also used as regulated food additives. [2] When in food or drink, sulfites are often lumped together with sulfur dioxide. [3]
The topic of sulfite food and beverage additives covers the application of sulfites in food chemistry. "Sulfite" is jargon that encompasses a variety of materials that are commonly used as preservatives or food additive in the production of diverse foods and beverages. Although sulfite salts are relatively nontoxic, their use has led to ...
Sulfites can cause allergies or sensitivities, says Purvi Parikh, MD, an allergist with Allergy & Asthma Network. However, this is rare. However, this is rare. Reactions can be more common in ...
To some extent, the sulfito ligand resembles nitrito (NO − 2), which can bind through N or O. Monodentate, S-bonded sulfites are more common than O-bonded sulfito ligands. S-Bonded sulfite is a soft ligand with a strongly trans labilizing effect as indicated by the rapid aquation of [Co(SO 3)(NH 3) 5] + to give [Co(SO 3)(NH 3) 4 (H 2 O)] +. [3]
breathing difficulty with low blood oxygen, potentially related to sulfite-containing compounded drugs. It also said sulfites may cause severe allergic reactions and life-threatening or less ...
Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na 2 SO 3. A white, water-soluble solid, it is used commercially as an antioxidant and preservative. A white, water-soluble solid, it is used commercially as an antioxidant and preservative.
Sodium metabisulfite, despite not being flammable, decomposes in 150 °C of heat releasing toxic gasses when decomposed. It is corrosive when dissolved in water. Some people who are sulfite sensitive may experience an allergic reaction to sodium meta bisulfite, sometimes severe, resulting in labeling requirements for food safety. [20]
A sulfite sulfate is a chemical compound that contains both sulfite and sulfate anions [SO 3] 2− [SO 4] 2−. These compounds were discovered in the 1980s as calcium and rare earth element salts. Minerals in this class were later discovered. Minerals may have sulfite as an essential component, or have it substituted for another anion as in ...
