Titanic acid
Chemical compound / From Wikipedia, the free encyclopedia
Titanic acid is a general name for a family of chemical compounds of the elements titanium, hydrogen, and oxygen, with the general formula [TiOx(OH)4−2x]n. Various simple titanic acids have been claimed, mainly in the older literature.[1] No crystallographic and little spectroscopic support exists for these materials. Some older literature refers to TiO2 as titanic acid,[2] and the dioxide forms an unstable hydrate when TiCl4 hydrolyzes.[3]
- Metatitanic acid (H2TiO3),[4]
- Orthotitanic acid (H4TiO4)[5] or Ti(OH)4. It is described as a white salt-like powder under "TiO2·2.16H2O".[6]
- Peroxotitanic acid (Ti(OH)3O2H) has also been described as resulting from the treatment of titanium dioxide in sulfuric acid with hydrogen peroxide. The resulting yellow solid decomposes with loss of O2.[7]
- Pertitanic acid (H2TiO4)[citation needed]
- Pertitanic acid ([TiO(H2O2)]2+)[8]
