Peroxydisulfate

Part of speech: noun

Definitions

1. A chemical compound consisting of two sulfur atoms and four oxygen atoms, often used as an oxidizing agent in various chemical reactions
2. It is a salt derived from peroxydisulfuric acid, commonly employed in analytical chemistry and industrial applications
3. This substance plays a role in the production of certain polymers and in the treatment of wastewater due to its strong oxidation properties

Etymology: Peroxydisulfate is a systematic chemical name, built by stacking the parts of its chemistry into one word. "Sulfate" names a salt of sulfuric acid, and "di-" marks two sulfur atoms, so the base is a dimer of sulfate units. "Peroxy-" marks the presence of an oxygen-oxygen bond, the same linkage found in hydrogen peroxide. Put together, the name describes the structure of the ion: two sulfate-like groups joined through a peroxide bridge. The "per-" prefix in chemistry signals extra oxygen, so a peroxide is a compound with more oxygen than its ordinary counterpart. That extra oxygen is what makes the ion a strong oxidizing agent, able to accept electrons from other substances. Salts of this ion, such as sodium and potassium peroxydisulfate, are used in industry to initiate polymerization and to bleach or etch materials.

Synonyms: persulfate, peroxydisulfate ion, peroxodisulfate, oxydisulfate
