Oxyanion with a central atom of sulfur surrounded by 3 oxygen atoms
Not to be confused with Sulfur trioxide.
A space-filling model of the sulfite anion.
Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), SO2− 3. 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]
