It is a common inorganic chemical reagent and is also used in photography and wood treatment. It is found naturally as the mineral lopezite. Hexavalent chromium refers to chemical compounds that contain the element chromium in the +6 oxidation state. Chromium(VI) is more toxic than other oxidation states of the chromium atom because of its greater ability to enter cells and higher redox potential. (L16, L55)"}]
