Extracting copper from malachite (copper carbonate) by using a redox reaction Aim Our aim is to extract copper from copper carbonate using a redox reaction. What is a redox reaction Reduction equals loss of oxygen Oxidation is the gain of oxygen O-Oxidation I-is L-loss OF ELECTRONS R-reduction I-is G-gain Prediction When I heat copper carbonate I expect it to turn from green to black because it's changing the copper oxide. The copper carbonate is being reduced. Copper oxide + carbon carbon dioxide + copper 2CuO C CO2 2Cu Black Pink Copper oxide will be reduced to turn into copper as it loses oxygen. This is called a redox reaction. (Science diagrams) Method 1. Put 1.5g of malachite powder into a large test tube and heat it gently until it turns black and stops rising in the test tube. 2. Allow the tube time to cool 3. Add 1.5g of carbon powder and mix well. 4. Heat the mixture strongly until it turns red and you can see some of the...
