Is Chromium(VI) oxide mainly used for electroplating? Is it highly toxic?

Yes! Chromium(VI) oxide is used mainly in electroplating. Hexavalent chromium is more toxic than other oxidation states of the chromium atom because of its greater ability to enter cells and higher redox potential. Chromium(VI) oxide is a known carcinogen. Chronic inhalation especially has been linked to lung cancer. It has also been known to cause reproductive and developmental defects.
