Hydrochlorotitanic Acid, H₂TiCl₆

Titanic chloride dissolves in concentrated hydrochloric acid, forming a yellow liquid which contains hydrochlorotitanic acid, H₂TiCl₆. Ammonium titanichloride, (NH₄)₂TiCl₆.2H₂O, forms in yellow crystals when the theoretical quantity of ammonium chloride is shaken with the hydrochloric acid solution of titanium tetrachloride; pyridine, quinoline, and aniline form similar complex salts.
