Chromic Acid

Chromic Acid CAS number : 7738-94-5 Synonyms : Chromic(VI) acid, Tetraoxochromic acid Molecular formula : H2CrO4 Molar mass : 118.01 g mol−1 Melting point : 197 °C, 470 K, 387 °F Boiling point : 250 °C, 523 K, 482 °F (decomposes)

The term chromic acid is usually used for a mixture made by adding concentrated sulfuric acid to a dichromate, which may contain a variety of compounds, including solid chromium trioxide. 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. 

 This is what happens when concentrated sulfuric acid is added to a dichromate solution. At first the colour changes from orange (dichromate) to red (chromic acid) and then deep red crystals of chromium trioxide precipitate from the mixture, without further colour change. The colours are due to LMCT transitions.
