1.Pour 25 mL of 0.5 M copper sulphate solution into a 50 mL beaker and put the beaker in the calorimeter.Insert the thermometer into the cover and fit the cover on the calorimenter.
2.Record the temperature of the solution.
3.Add 0.25 g of Zn powder into the solution and stir.
4.Observe the temperature changes.Record the highest temperature reached during this reaction.Is the reaction exothermic or endothermic?
5.Pour the solution into a beaker in order to observe any changes that may occur.Record your observation.
6.Clean the calorimeter thoroughly with water, then add anther 25 mL of copper sulphate solution.Repeat the experiment for a second trial.
7.Repeat step 1-6 but change the amount of Zn powder to 0.5,1 and 2 grams.
8.Construct a graph by plotting the amount of zinc on the x-axis and the recorded temperature on the y-axis.
