Iron(III) chloride, FeCl3, also known as ferric chloride, is commodity chemical. As the hydrated salt (nominally a hexahydrate, FeCl3·6H2O), it is used in water purification and as an etchant for printed circuit boards.[2] The anhydrous compound is a moderately strong Lewis acid and is used in organic synthesis.
