To investigate the temperature change in a displacement reaction between Copper sulfate Solution and Zinc PowderPreliminary ExperimentCorrelating milligram Powder and Copper Sulphate Solution=========================================================I go forth mix 4cm of Magnesium ornamentation and 50cm of Copper SulphateSolution into a polystyrene cup until I find a reaction.===============================================================Prediction==========The magnesium pass on displace the copper and the temperature will rise.Magnesium + Copper Sulphate Copper + Magnesium------------------------------------------------Mg + CuSO4 Cu + MgSO4Hypothesis==========The Magnesium will displace the Copper and rise in temperature becauseit is more than reactive and it is an heat-releasing reaction.Results=======Start Temperature 22CEnd Temperature 28CRise In Temperature 6CThis preliminary experiment was very utile because it is clear thatthere was a very s mall rise in temperature. This give the sack be solved byusing the powdered form of metal, that can be used to increase thesurface area.Main Experiment================Correlating Zinc and Copper Sulphate Solution=============================================Prediction==========I predict that the atomic number 30 will displace the copper to become zincsulfate.---------------------------------------------------------------Zinc + Copper Sulphate Zinc Sulphate + CopperI predict that the copper sulphate will only partially be fire upedduring the reaction depending on the mass of zinc added to thesolution of 50ml3.I predict that this reaction of the zinc and copper sulphate will beexothermic, therefore it will produce its own heat.I predict that the zinc powder will release more heat than zinc decoration.I predict that the more zinc added to this reaction, the more thetemperature would become up to a certain point.I predict that the temperature will increase when adding more zincuntil a certain mass of zinc is reached. If more zinc is added whenthe peak has been reached, then the temperature will decrease.Hypothesis==========The copper will be displaced because zinc is higher in the reactivityseries than copper therefore zinc is more reactive.The copper sulphate solution will only partially be heated during thereaction because there is not enough zinc to react with all of thecopper depending on the mass of zinc.This reaction will be exothermic because all the heat will be givenoff in this reaction.The zinc powder will release more heat than zinc ribbon due to thepowder having a larger surface area.The peak temperature is when there is about enough zinc to react withthe copper sulphate. Any less zinc and it would not react as muchproducing less heat. Any more zinc would leave excess amounts, whichwould be harder to heat up and will lose weight temperatures.
