Reactivity series for common metals experiment Essay

AimTo charm if a common alloy is reactive or strong enough to replace/push come in/ rout out another common surface from its liquid compound.HypothesisMy prediction will be the or so reactive metallic element shown by the reactivity serial will show if the metal can displace or not the metal in the compound. For example my hypothesis in a answer of Mg and Pb is that Mg being a more reactive metal in the reactivity series will displace Pb, a least reactive metal in the series.Equipment1. A chart with spaces bouffant enough to proceed with the reaction. With the names of each different metals. For obvious reasons put an x from the top left over(p) corner to the inferior left corner.2. A glass bigger than the chart for the paper for protection of it.3. apiece solid metal and metal compound for the reaction Solid surfaces Magnesium (4), blur(4), Iron(4), Zinc(4), Lead(4). Liquid Metal Compounds hair Sulphate, Iron Chloride, Magnesium Sulphate, Zinc Nitrate, Lead Nitrate.4. A titty pipette.5. Another table, but smaller, to record data. mathematical operation/Method1. Get all required elements you are going to need, this elements are listed above.2. Put the glass on top of the table of reactions.3. Clean all metals, until they are shiny and sluttish.4. Place 4 times the same metal on its corresponding column and different square for all the metals(5).5. Add carefully with the teat pipette one or two drops of the metal compound indicated directly onto the solid metal.6. Observe for changes, confine into account that if the texture or color are altered, it means that in that location has been displacement, reaction.7. create verbally your observations.8. Results should be scripted in a neat table, as tick if on that point was reaction, X if there was none and ? If not sure.9. Analyze and conclude from your data.Data AnalysisFrom the table above, we can conclude that the most reactive metal is Magnesium (Mg), since it reacts with all the metal compou nds except itself (Magnesium Sulphate). Then will come Zinc (Zn) , reacting with 2 Metal Compounds. Iron(Fe) will be less reactive than Zn and reacting with only 1 Metal Compound. Finally the least reactive Solid Metal will be Copper and Lead, reacting with none metal compounds.Conclusion1. Write down the determine of reactivity you foundBased on the graphic above the reactivity order i found3. Suggest why some squares were tag with an X on the grid.The diagonal squares in the grid from top left hand corner to lower right hand corner were marked with an X because it is pretty obvious that a metal can not displace the same metal on the compound because it has the same reactivity and atoms on the last shell in the atom. So for example, Copper will not displace Copper on the compound Copper Sulphate.4. Referring to your text book. Is there any metal that does not seem to be behaving as its position says it should? Can you find any reasons for this?Well referring to the reaction seri es there are some metals i found which do not fit in the reaction series, this are Copper and Lead well copper and lead should not be tied, the reactivity series show that Lead is more reactive than copper, and by this it should be world-class in the reactivity order.i think there are 2 possible ways to formulate why this happensSince the results we did were not very accurate and Lead and Copper are very close in the reactivity series, maybe we did not noticed the reaction of Lead or Copper, or maybe there wasnt in neither of them, well it is very possible that the reaction of them was not too noted to see the difference between them, but even though there was.The other possible way, could be that the metals werent very clean before we tested them, and so this could have altered and prevented a reaction in Lead.EvaluationIn general we did a great effort with my teammate in the lab, we employ exactly two drops of the metal compound to the metal solid, tried every metal to be clea n , but unfortunately we needed machinery to polish every single metal but we did not had it, we entirely had to do our best at trying to polish them.Another problem we did had, was to handle the spaces and the arrangement of the metals within their boxes in the lab well we applied a small square to each experiment, we frequently had the metal compound spreading into other boxes, damaging the fair results of the other experiments. One solution could be to nurse bigger spaces and arrange each metal at the center of its box.
