Chloroplatinic acid (also known as hexachloroplatinic acid) is an inorganic compound with the formula [H₃O]₂[PtCl₆](H₂O)_x (0 ≤ x ≤ 6). A red solid, it is an important commercial source of platinum, usually as an aqueous solution. Although often written in shorthand as H₂PtCl₆, it is the hydronium (H₃O⁺) salt of the hexachloroplatinate anion (PtCl²⁻
₆). Hexachloroplatinic acid is highly hygroscopic.
