Evaluation I conducted an experiment to find out the enthalpy changes that took place for the reaction between copper sulphate and zinc. An enthalpy change of a reaction is the heat exchange with the surroundings at constant pressure. Introduction In this experiment in order to find out the enthalpy change I shall be reacting aqueous copper sulphate with zinc. In this reaction Cu is being reduced and Zn is being oxidised. In this experiment the enthalpy change is exothermic. Enthalpy changes can be both exothermic and endothermic. Exothermic reactions are easily recognised by a rise in temperature. Endothermic reactions require an energy input. Enthalpy is the total energy content of the reacting materials it is given the symbol H. Enthalpy cannot be measured but it is possible to measure enthalpy change when energy is transferred to or from a reaction system. Enthalpy change is given the symbol ?H where ? is pronounced as change. ?H = H...
