WebChromic acid, also known as Jones reagent, is prepared by adding chromium trioxide (CrO 3) to aqueous sulfuric acid. The Jones oxidation also uses acetone as a co-solvent in the reaction to prevent over-oxidation of the organic product. A mechanism for the chromic acid oxidation of a ketone is shown below. WebMar 1, 2024 · Chromium ions are found in nature in two stable oxidation states: Cr(III) and Cr(VI). In aquifers, Cr(VI) is thermodynamically favored under oxidizing conditions and is highly soluble in water. In the absence of ligands other than OH- and H 2 O, HCrO 4 − and CrO 4 2− oxyanions are the most stable Cr(VI) species in groundwaters [ 1 ].
