CHROMIUM TRIOXIDE, CRYSTAL, REAGENT, ACS is a flaky dark purple solid when anhydrous and turns orange when when wet. Its main use is in chrome-plating. Typically used with additives during the plating process that do not affect the trioxide, it can also be used with chromic acid to apply certain types of anodic coating to aluminum. As an ACS grade quality reagent, its chemical specifications are the de facto standards for chemicals used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. Spectrum Chemical manufactured Reagent ACS grade products meet the toughest regulatory standards for quality and purity.
