displacement reactions of metal

Extracts from this document...

Introduction

Lab Report on Displacement Reactions of Metals * Hypothesis I can predict that a more reactive metal will displace a less reactive metal from its salts. To predict the displacement, I have applied the knowledge of reactivity and this is my prediction: Copper Magnesium Iron Zinc Magnesium Iron Zinc Copper Magnesium will displace zinc, iron and copper as it is a very reactive metal. Zinc will displace iron and copper but not magnesium as magnesium is more reactive. Iron will displace copper only as it is a less reactive metal. ...read more.

3. Then the reaction took place and I noted the results and the observations. * Results & Observations Metals + Aqueous solutions Results 1. Copper + Magnesium sulphate No reactions 2. Copper + Iron sulphate No reactions 3. Copper + Zinc sulphate No reactions 1. Magnesium + Iron sulphate Bubbles were formed, it had a very fast and violent reaction, dissolves & changed in colour green. 2. Magnesium + Copper (II) sulphate Part of the magnesium ribbon dissolves, remaining of it became coated with layer of reddish brown copper metal. ...read more.

Conclusion

This displacement reaction is also known as redox reaction. And I would like to give an example: In the reaction between magnesium and copper II sulphate, magnesium reduces the copper II ion, Cu , to copper and is itself oxidized to the magnesium ion, Mg . The ionic equation is as follows: Mg(s) + Cu (aq) Mg (aq) + Cu(s) Silver reddish brown This experiment also allows us to see that a metal that is in higher position in the reactivity series is related to the tendency of the metal to form an + ion. ...read more.

Response to the question

Overall conclusion and body of the text are set out adequately for this level of qualification, but I would like to see the science of redox reactions explained more in the introduction. The introduction is set out okay but lacks the detailed scientific knowledge that I would like to see for this level. Main body and method are set out okay, with observations and the method noted clearly. In the main body I would like the student to explain why there was no reaction seen in certain instances, as this is due to no displacement of metals but the author does not demonstrate this simple fact. Conclusion is set out okay with a good equation to finish although I would like to see them use more examples from the main body of their coursework to support their conclusions, also could be worded slightly clearer.

Level of analysis

Level of analysis could be deeper, adequate for the middle scale of this level and the understanding of displacement reactions and redox is clearly shown but I would like to see more detailed scientific analysis throughout. Could display additional skills such as graphs, or adding an evaluation of the experiment.

Quality of writing

Spelling, punctuation and grammar okay, with no little to no mistakes seen. Could be a bit clearer in the presentation of results.

    and so there will be more successive collisions. So increasing the concentration will increase the probability (chance) of particles colliding because there would be more particles crowded together in the same volume and so there would be more collisions - increased rate or reaction.

    It shows how the temperature increase levels off at around 23 degrees. It has reached its full peak when the mass of zinc is 2.0g. As this is a displacement reaction it means that the whole purpose of it is that Zinc is trying to take something away ffrom the copper (ii)

    For the copper sulphate concentration of 0.4mols the average amount of oxygen produced between 10 and 20 seconds was extraordinarily high; on average 0.6cm3 of oxygen was produced in those 10 seconds. The reason the average amount of oxygen produced was relatively high is due to one anomalous result.

    8. Repeat experiment for accurate results. Safety There is a possible hazard when carrying out this experiment as the copper sulphate solution or the zinc sulphate solution could be an irritant to the skin therefore contact with the skin should try to be avoided. Goggles must also be worn to protect any harmful substances from entering your eyes.

    To make sure that all my results are as accurate as possible I will do each experiment three times and then take an average to prevent any anomalous results affecting the end conclusion in a big way. Safety The safety of this experiment is very important.
