Titanic acid explained

Titanic acid is a general name for a family of chemical compounds of the elements titanium, hydrogen, and oxygen, with the general formula . 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 as titanic acid,^[2] and the dioxide forms an unstable hydrate when TiCl₄ hydrolyzes.^[3]

• Metatitanic acid,^[4]
• Orthotitanic acid ^[5] or . It is described as a white salt-like powder under "".^[6]
• 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 .^[7]
• Pertitanic acid
• Pertitanic acid ^[8]
