Description: Chromium is a hard, blue-white metal. It will dissolve in HCl and H2SO4 but not in HNO3, H3PO4 or HClO4 due to reaction and formation of a protective layer on the surface. Chromium can be polished to a high shine and resists oxidation in air. It main uses are in alloys, chrome plating and metal ceramics.
