After heating the mixture for some time, the mixture suddenly lights up and glows. Amongst the reaction products is red-golden Copper.



Copper Oxide is reduced to elementary Copper by Zinc. The Zinc is oxidized and becomes Zinc Oxide.



Reduction: Cu2+ +2e- -> Cu +



Oxidization: Zn -> Zn2+ +2e-



CuO + Zn -> ZnO + Cu
