Chromium 6 compounds
WebHexavalent chromium refers to compounds where chromium is present in +6 oxidation state. Hexavalent chromium is commonly referred to as: chromium 6, chromium VI, chrome 6, Cr(VI), Cr+6, or hex chrome. Hexavalent chromium is also popularly known as the “Erin rockovich chemical” after WebChromium exists in a wide range of oxidation states. Most common are the oxidation states: +2, +3, and +6. Chromium (II) is not stable and is a strong reducing agent. It should be noted, the most stable oxidation state for chromium compounds is +3. Moreover, it can also exist in the oxidation states +1, +4, and +5. However, these are much rarer.
