WebChromic acid H2CrO4 or CrH2O4 CID 24425 - structure, chemical names, physical and chemical properties, classification, patents, … WebChromic acid (H 2 Cr 2 O 7 (aq)) is a strong acid because hydrogen ions disassociate and stay in solution. This is why (aq), meaning “aqueous”, is written after its formula. 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).
