How factors influence the energy change when metals are added to a metal salt solution? Skill P : Planning Experiments Aim: My aim is to see what factors influence the energy change when metals are added to a metal salt solution. Introduction: The energy released when one metal displaces another can be used in industry, for example in the reaction of aluminium with iron oxide to weld rails together. Your task is to devise a plan to show how the temperature rise, and hence the energy cange, is affected by adding different metals to copper sulphate solution. A suitable metal woould be iron, which reacts according to the equation: Fe(s)+CuSO4(aq)?FeSO4(aq)+Cu(s) Prediction: In my experiment, I can predict that when we add different metals to the Copper Sulphate liquid in forms of powder, the temperature will rise when the reaction takes place, in the polystyrene cup. The more reactive the metal the more the temperature produced, so the...
