This kind of chromic acid may be used as a cleaning mixture for glass. Chromic acid may also refer to the molecular species, H2CrO4 of which the trioxide is the anhydride. Chromic acid features chromium in an oxidation state of +6 (or VI). It is a strong and corrosive oxidising agent. IUPAC name: Chromic acid. Systematic name: Dihydroxidodioxidochromium. Other names: Chromic(VI) acid; Tetraoxochromic acid) |
