Investigating how the mass of iron fillings affects the mass of copper displaced from copper sulphate.

Extracts from this document...


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 20cm� 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 of the Iron Filings into the filter funnel and allow to filter. 8. When the Copper Sulphate has filtered out, take out the filter paper and allow it to dry. ...read more.


4. Then I measured out 0.5g of Iron fillings on to the filter paper. 5. When I had the essential amount of Iron Fillings, I poured them into the beaker with Copper Sulphate in and started timing with the stopwatch simultaneously. 6. Whilst the stopwatch was running, I stirred the iron filings slightly with the stirring rod, and also folded the filter paper so that it was ready to be fitted into the filter funnel. 7. When 3 minutes had gone, I stopped the stopwatch and then poured the every thing from the beaker into the filter funnel and allowed the copper sulphate to filter out. 8. Once the Copper Sulphate had filtered out, I took out the filter paper and allowed it to dry on the windowsill. 9. I then repeated the investigation from step 2 twice more, but instead I used 0.75g and 1.0g. * The whole experiment was completed twice to get reliable results. From the experiment I observed that after 3 minutes, the Iron Filings that I had put into the Copper Sulphate had become coated by Copper. ...read more.


The results that I did collect were not the most reliable in the world. Even though I repeated the experiment twice the results for the 0.5g of iron filings showed rather different outcomes. The 1st time showed 0.58g, but the 2nd time showed 0.53g. This probably happened as some of the copper, which was drying, was probably knocked off the filtering paper. There was nothing I could have done about this, as I was not able to look after them. There were not really any improvements I could have done to the actual experiment, as it was a relatively simple procedure. It was not really possible to make any improvements, unless I had done something to ruin my results, like add too much iron filings, etc. The only thing I could of done was to look after my drying copper, but this was not possible. There are a couple of things that I could do for extra work. One is to find out if more copper is displaced from the copper sulphate if the concentration of it is higher. Another experiment that I could do would be to change the salt solution that I used. I could have also used another metal of the reactivity series. ...read more.

    Safety As always, the normal laboratory rules will apply during this experiment, for example, blazers and scarves to be kept outside, long hair tied back and the workbenches being kept clear. Because both copper sulphate solution and zinc powder are irritant, it is important to wear safety goggles throughout the experiment.

  1. Investigate a factor that effects the change in temperature between iron and copper sulphate.

    The more iron added to the copper sulphate the more iron molecules there are colliding and reacting with the copper molecules, increasing the rise in temperature. I predict in this experiment that the rise in the mass of iron will be directly proportional to the rise in temperature; this being
