, with the general formula . Various simple titanic acids have been claimed, mainly in the older literature. No crystallographic and little spectroscopic support exists for these materials. Some older literature including Brauer's Handbook refers to as titanic acid. *''Metatitanic acid'' (), *''Orthotitanic acid'' () or . It is described as a white salt-like powder under "". *''Peroxotitanic acid'' () 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 . *''Pertitanic acid'' () *''Pertitanic acid'' ()
