Sulfite Wikipedia

Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), SO 2 3.The sulfite ion is the conjugate base of bisulfite.Although its acid (sulfurous acid) is elusive, 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.
