Calcium chromate dihydrate
Calcium chromate is a chemical compound of calcium and hexavalant chromium. It is used as a pigment, a corrosion inhibitor, and in electroplating, photochemical processing, and industrial waste treatment. 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, L52)
