The Jones oxidation uses chromium trioxide (CrO₃), acid, water, and acetone to convert 1° or 2° alcohols into carboxylic acids or ketones respectively. Chromic acid is first prepared by dissolving CrO₃ or Cr₂O₇^2- in acid: the monomeric form (HCrO₄^-) dominating in dilute solutions versus the dimeric form (HCr₂O₇^-) dominating in concentrated solutions. Alcohol makes a chromate ester with HCrO₄^-, eliminating HCrO₃^- to yield the carbonyl compound.
