potassium dichromate (Cr2O7^2-) oxidation of ethanol to acetic acid is the basis for the original breath-alcohol screening test used by law enforcement agencies to determine a person's blood alcohol content (BAC). the test is based on the difference in colour between the dichromate ion( redish orange) in the reagent and the chromium(iii) ion (green) in the product. deduce the reaction that is involved in this test and give the IUPAC name of the other product formed.
