- 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.
