Chromium(VI) oxide, also known as chromic oxide or chromium trioxide, is a chemical compound with the formula CrO3. It appears as a dark red or purple solid and is highly soluble in water. This compound is primarily used in the production of pigments, particularly in the manufacture of paints and dyes, due to its vibrant color. In addition to its use in pigments, Chromium(VI) oxide is also employed in various industrial processes, including metal finishing and the production of chromium salts. However, it is important to note that Chromium(VI) compounds are toxic and carcinogenic, necessitating careful handling and regulation in industrial applications.
