An investigation into the displacement of metals (reacting masses) Aim: I am investigating how the mass of iron fillings affects the mass of copper displaced from copper sulphate. Apparatus: Iron filings, copper sulphate, beaker, stirring rod, goggles, scale, filter funnel, filter paper, evaporation dish. The variable that I will be changing is the mass of Iron Filings (in grams) added to the Copper Sulphate. Plan: 1. Collect all appropriate apparatus and then set up. 2. Carefully pour 20cm³ of Copper Sulphate into a beaker. 3. Place a sheet of filter paper on to the scales and then set scales to zero. 4. Measure out 0.5g of Iron Filings on to the filter paper by reading the scales. 5. Pour the Iron Filings into the beaker whilst simultaneously starting the stopwatch. 6. Whilst the stopwatch is running, fold the filter paper so that it fits into the filter funnel. 7. When 3 minutes has gone, stop the stopwatch and pour all...
