Reactivity series for common metals experiment Essay
AimTo set if a parking lot surface is labile or strong abundant to replace/ get-up-and-go out/ end a nonher common surfacelic element from its liquid compound.HypothesisMy prognostication provide be the most unstable metallic element shown by the reactivity serial publication will show if the metal crowd out displace or non the metal in the compound. For example my hypothesis in a chemical response of Mg and Pb is that Mg being a much unstable metal in the reactivity series will displace Pb, a least reactive metal in the series.Equipment1. A graph with spaces big enough to proceed with the reaction. With the names of each unlike metals. For unequivocal reasons put an x from the covering leftfield quoin to the inferior left receding.2. A grump larger than the chart for the paper for protection of it.3. Each self-coloured metal and metal compound for the reaction Solid metals Magnesium (4), hog(4), Iron(4), surface(4), Lead(4). Liquid surface Compounds c opper Sulphate, Iron Chloride, Magnesium Sulphate, Zinc Nitrate, Lead Nitrate.4. A teat pipette.5. some otherwise delay, save smaller, to record data.Procedure/method acting1. Get 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. causely all metals, until they are shiny and low-cal.4. frame 4 times the same metal on its corresponding column and divers(prenominal) square for all the metals(5).5. Add conservatively with the teat pipette one or two drops of the metal compound indicated straightaway onto the solid metal.6. Observe for changes, take into theme that if the texture or color are altered, it means that there has been displacement, reaction.7. Write your observations.8. Results should be written in a dandy table, as tick if there was reaction, X if there was none and ? If not sure.9. break apart 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 only 1 Metal Compound. in conclusion the least reactive Solid Metal will be Copper and Lead, reacting with none metal compounds.Conclusion1. Write downhearted the order of reactivity you foundestablish on the graphic above the reactivity order i found3. counsel why some squares were marked with an X on the football field.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 all metal that does not seem to be b ehaving as its position says it should? Can you come upon any reasons for this?Well referring to the reaction series there are some metals i found which do not move in the reaction series, this are Copper and Lead well copper and occur 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 contingent slipway to explain why this happensSince the results we did were not rattling accurate and Lead and Copper are very close in the reactivity series, possibly we did not noticed the reaction of Lead or Copper, or maybe there wasnt in uncomplete of them, well it is very possible that the reaction of them was not too noticeable to see the difference between them, but evening though there was.The other possible way, could be that the metals werent very clean before we tested them, and so this could birth altered and prevented a reaction in Lead.EvaluationIn general we did a gr eat effort with my teammate in the lab, we applied exactly two drops of the metal compound to the metal solid, tried either metal to be clean , but unfortunately we needed machinery to polish every(prenominal) single metal but we did not had it, we just had to do our best at trying to polish them.Another line of work 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 a great deal had the metal compound spreading into other boxes, damaging the fair results of the other experiments. oneness solution could be to apply bigger spaces and arrange each metal at the center of its box.
