WebThe chromium (V) acid promotes a two-electron oxidation of an alcohol and becomes Cr (III). Any residues of toxic Cr (V) and Cr (VI) compounds can be destroyed by the addition of an excess of 2-propanol once the intended reaction is complete. The formation of Cr (III) is indicated by a color change to green. Webare: COR75-AQ-001, COR75-AQ-010, COR75-AQ-066 and COR75-AQ-393. COR75-AA-011 Series is UL 1746-approved.
