GCSE Chemistry An Investigation Into How the Mass of Zinc Effects the Heat Change In the Displacement Reaction Between Zinc and Copper Sulphate This investigation aims to look at how a factor can change the amount of heat produced in a displacement reaction. The displacement reaction that will occur during this experiment will be an exothermic reaction, which will mean that heat will be given out to the surroundings. The possible independent variables that could be investigated are: * The mass of zinc * The pressure of the surrounding atmosphere * The concentration of the copper sulphate * The surface area of the solid reactant, i.e. the zinc * The volume of copper sulphate * The light intensity * The pH of the copper sulphate I have chosen to vary the mass of the zinc, as it is simple and easy to measure and control. Therefore the controlled variables will be: * The concentration of the copper sulphate * The...
