Cobalt trichloride, with the chemical formula CoCl3 and CAS number 10241-04-0, is an inorganic compound characterized by its striking color change properties. It typically appears as a blue or violet solid in its anhydrous form, but when hydrated, it can take on a pink hue, particularly in its hexahydrate form (CoCl3·6H2O). This compound is known for its hygroscopic nature, meaning it readily absorbs moisture from the environment. Cobalt trichloride is often used as a moisture indicator and in various chemical applications, including as a catalyst in organic synthesis. It exhibits paramagnetic properties due to the presence of unpaired electrons in its cobalt ions. Additionally, cobalt trichloride is soluble in water, and its solutions can be used in electroplating and as a precursor for other cobalt compounds. However, it should be handled with care, as cobalt compounds can be toxic and pose health risks upon exposure.
