CrCl3, or chromium(III) chloride, is an inorganic compound consisting of chromium and chlorine. It typically appears as a green or purple solid and is soluble in water. This compound is often used in various applications, including as a catalyst in chemical reactions and in the production of pigments. In its hydrated form, CrCl3·6H2O, it is commonly used in laboratories and industrial processes. Chromium, the central element in CrCl3, is a transition metal known for its hardness and resistance to corrosion, making it valuable in metallurgy and manufacturing.
