http://www.commonorganicchemistry.com/Common_Reagents/Chromium_Trioxide/Chromium_Trioxide.htm WebWhat is cro3 used for? Chromium trioxide is mainly used in chrome plating. It is typically employed with additives that affect the plating process but do not react with the trioxide. The trioxide reacts with cadmium, zinc, and other metals to generate passivating chromate films that resist corrosion.
