Introduction: * Through my preliminary work I have found the following ways of producing samples of Copper Oxide: 1. Heating Copper powder/turnings in air. 2. Heating Copper Carbonate in air. 3. Heating Copper Hydroxide in air. 4. Heating Copper Nitrate in air. 5. Heating Copper Sulphate in air * Experiments 1, 2 and 3 are all suitable methods of producing Copper Oxide. * I have decided not to perform either of the last two ways because both give off poisonous gasses during production. * I have chosen to perform the following 3 different experiments: 1. Reducing a pre-prepared lab sample of Copper Oxide 2. Reducing a sample made by heating Copper Carbonate in air 3. Oxidation of Copper Powder Prediction: * I believe that the formula of Copper Oxide will remain the same (i.e....
