Aim: To investigate the temperature change in a displacement reaction between Copper Sulphate Solution and Zinc Powder Preliminary Experiment: Correlating Magnesium Powder and Copper Sulphate Solution I will mix 4cm of Magnesium ribbon and 50cm³ of Copper Sulphate Solution into a polystyrene cup until I find a reaction. Prediction The magnesium will displace the copper and the temperature will rise. Magnesium + Copper Sulphate › Copper + Magnesium Mg + CuSO4 › Cu + MgSO4 Hypothesis The Magnesium will displace the Copper and rise in temperature because it is more reactive and it is an exothermic reaction. Results Start Temperature 22°C End Temperature 28°C Rise In Temperature 6°C This preliminary experiment was very useful because it is clear that there was a very small rise in temperature. This can be solved by using the powdered form of metal, that can be used to increase the surface area. Main Experiment: Correlating Zinc and Copper Sulphate Solution Prediction I predict that the zinc will displace the copper to become zinc sulphate. Zinc...
