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. Some simple titanic acids have been identified, such as metatitanic acid (H
2TiO
3),[1] and orthotitanic acid (H
4TiO
4).[2] Orthotitanic acid is a white salt-like powder under normal conditions.
The amphoteric compound is insoluble in water. Alkali metal and alkaline earth metal hydroxides react with it to form the corresponding salts, most notably strontium titanate.
