Reactivity series for common metals experiment Essay
AimTo see if a common surface is reactive or strong enough to replace/push out/ evict a nonher common admixture from its liquid change.HypothesisMy prediction depart be the most reactive surface shown by the reactivity serial will show if the admixture can displace or not the metal in the heterogeneous. For example my hypothesis in a reception 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 outsized enough to proceed with the reaction. With the names of each different metals. For obvious reasons drift an x from the top left corner to the inferior left corner.2. A water ice bigger than the chart for the paper for protection of it.3. Each red-blooded metal and metal compound for the reaction Solid coats Magnesium (4), Copper(4), Iron(4), Zinc(4), superstar(4). liquefiable Metal Compounds Copper Sulphate, Iron Chloride, Magnesium Sulphate, Zinc Nitrate, L ead Nitrate.4. A titmouse pipette.5. some other postpone, but sm solelyer, to record data.Procedure/Method1. drum all required elements you be 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 glazed and clean.4. Place 4 times the same metal on its comparable 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 straightway onto the solid metal.6. Observe for changes, take into account that if the texture or pretense are altered, it means that at that place has been displacement, reaction.7. economize your observations.8. Results should be written in a neat table, as tick if in that location was reaction, X if thither 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 compounds 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 just now 1 Metal Compound. Finally the least reactive Solid Metal will be Copper and Lead, reacting with none metal compounds.Conclusion1. Write down the order of reactivity you foundBased on the in writing(p) above the reactivity order i found3. Suggest wherefore some squares were marked with an X on the storage-battery grid.The diagonal squares in the grid from top left sacrifice 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 r easons for this?Well referring to the reaction series there are some metals i found which do not fit in the reaction series, this are Copper and Lead tumefy copper and lead should not be tied, the reactivity series show that Lead is more reactive than copper, and by this it should be first in the reactivity order.i think there are 2 possible ways to explain why this happensSince the results we did were not very accurate and Lead and Copper are very plastered in the reactivity series, maybe we did not noticed the reaction of Lead or Copper, or maybe there wasnt in incomplete of them, well it is very possible that the reaction of them was not too evident 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 married person in the lab, we applied exactly two drops of the metal compound to the metal solid, tried every metal to be clean , but alas we needed machinery to polish every single metal but we did not had it, we just 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. unmatchable solution could be to apply bigger spaces and arrange each metal at the center of its box.
