GSCE Chemistry coursework Investigating the reaction between zinc and copper sulphate solution Theory When two substances react, one of three things can happen. The reaction might be exothermic, and produce a lot of energy for a small activation input. It might be endothermic, and absorb heat energy from the environment in order to react. They could, of course, just not react at all. Copper sulphate and zinc is what I will be investigating, and I will measure the temperature given off to record the rate of reaction. I expect that the two chemicals will produce an exothermic reaction, purely because zinc is far more reactive than copper and it will displace the copper creating heat. Method To do the experiment I will need the following equipment: * Powdered zinc * Copper sulphate solution (0.5M) * Measuring cylinder * Timer * Weighting scales * Polythene cups * Periodic table * Thermometer I will be recording the temperature given off during the experiment. I could have...
