[O][Cr][=Branch1][C][=O][=Branch1][C][=O][O]"}, {"from": "gpt", "value": "The molecule is more toxic than other oxidation states of the chromium atom because of its greater ability to enter cells and a higher redox potential. (9) Molecular chromic acid, H2CrO4, has much in common with sulfuric acid, H2SO4 as both are classified as strong acids. Chromic acid was widely used in the instrument repair industry, due to its ability to \"brighten\" raw brass. A chromic acid dip leaves behind a bright yellow patina on the brass. Due to growing health and environmental concerns, many have discontinued use of this chemical in their repair shops.  Most chromic acid sold or available as a 10% aqueous solution."}]
