Investigation of the effect of the mass of Zinc, on the temperature change of a Copper Sulphate solution

Note: I couldn't paste in pictures and diagrams so please excuse any large spaces. Planing my investigation Method 1.Firstly I will measure 20ml of Copper Sulphate solution (CuSO4) in a measuring cylinder, for precise accuracy, and then pour the solution into test tube. I will place the test tube into a beaker and insulate the test tube, for minimum heat loss. (As shown in the diagram above.) 2.Secondly I will measure the required amount of …

…better plan: *I could use a funnel to pour Zn and CuSO4 into the beaker to minimise loss of reactants *I could time the reaction so all experiments have an equal time to react *I could repeat the experiment further for a better average For further work to provide additional evidence, I could redo the experiment but investigate the effect of Zn on different volumes of CuSO4, and see what differences take place then.
