Hexafluorotitanic acid (systematically named oxonium hexafluoridotitanate(2-)) is an inorganic compound with the chemical formula (H3O)2[TiF6].As with most oxonium salts it is not stable when undissolved or under neutral to basic conditions tending to decompose in those conditions to titanium fluorides or oxyfluorides. Under highly acidic conditions it decomposes to titania which accelerated by fluoride scavengers. Under highly basic conditions it is hydrolysed to titanium hydroxide.
