Formula: Cr2(Cr2O7)3 = Cr8O21
Chromic acid is the acid in chromic acid. The chemical formula is H2CrO3 (Not correct)Added & Corrected:Often the species are assigned the formulas H2CrO4 (dihydrogen chromate) and H2Cr2O7 (dihydrogen dichromate).The anhydride of these "chromic acids" is chromium trioxide, also called chromium(VI) oxide (2CrO3=Cr2O6).Regardless of its exact formula, chromic acid features chromium in an oxidation state of +6 (or VI), the highest known.
H2Cr207 is also known as chromic acid.
