Peroxymonosulfuric Acid
  • Peroxymonosulfuric acid, , also known as persulfuric acid, peroxysulfuric acid, or Caro՚s acid.
  • In this acid, the S (VI) center adopts its characteristic tetrahedral geometry; the connectivity is indicated by the formula
  • It is one of the strongest oxidants known () and is highly explosive.
  • Is sometimes confused with , known as peroxydisulfuric acid.
  • Disulfuric acid, which appears to be more widely used as its alkali metal salts, has the structure

Structures for

  • It is tetrahedral structure.
  • being an inorganic acid only one structure is possible for
  • Like i, sulfur in i molecule is in hybridized state.
  • So, it will adopt tetrahedral structure. Both in and is in + 6 oxidation state.
  • Compare with methane. Put sulfur as central atom. Two apexes of the terahedron will be occupied by two-oxygen atom (double bonded oxygen) . One apex will be occupied by -OH. Remaining will be occupied by peroxy bond (-O-OH) .
  • It contains two double bonded oxygen atoms, which are attached to the Sulphur atom and two -OH groups.

Uses in Industry

  • Has been used for a variety of disinfectant and cleaning applications, e. g. , swimming pool treatment and denture cleaning.
  • Alkali metal salts of show promise for the delignification of wood
  • It is also used in laboratories as a last resort in removing organic materials since can fully oxidize any organic materials
  • Ammonium, sodium, and potassium salts of are used in the plastic industry as polymerization initiators, etchants, desizing agents, soil conditioner, and for decolorizing and deodorizing oils.
  • Potassium peroxymonosulfate, is the potassium acid salt of peroxymonosulfuric acid. It is widely used as an oxidizing agent.
