Cerium(III) chloride (CeCl3) also known as cerous chloride or cerium trichloride is a compound of cerium and chlorine. It is a white hygroscopic solid; it rapidly absorbs water on exposure to moist air to form a hydrate which appears to be of variable composition though the heptahydrate CeCl3·7 H2O is known. It is highly soluble in water and (when anhydrous) it is soluble in ethanol and acetone.
