Sodium Sulfites - an overview | ScienceDirect Topics

The Wellman-Lord process uses sodium sulfite to absorb SO 2, which is then regenerated to release a concentrated stream of SO 2.Most of the sodium sulfite is converted to sodium bisulfite by reaction with SO 2, as in the dual alkali process.Some of the sodium sulfite is oxidized to sodium sulfate.

What Is the Difference Between Sulfate, Sulfide and Sulfite?

Sulfates, also spelled sulphates, are used in a variety of common products and processes. Sodium lauryl sulfate is a strong detergent used for removing oils and grease and is found in cleaning products, face and body washes and shampoos. Sodium sulfate is used in the manufacturing of glass and paper. Zinc sulfate is used to preserve wood.

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.
