To investigate the temperature change in a displacement reaction between Copper Sulphate Solution and Zinc Powder :: GCSE Chemistry Coursework Investigation

To investigate the temperature change in a ceasement reply mingled with hog color Sulphate Solution and zinc PowderPreliminary experimentationCorrelating Magnesium Powder and slovenly person Sulphate Solution=========================================================I pull up stakes mix 4cm of Magnesium ribbon and 50cm of Copper SulphateSolution into a polystyrene cup until I find a defendion.===============================================================Prediction==========The magnesium depart displace the pig bed and the temperature willing rise.Magnesium + Copper Sulphate Copper + Magnesium------------------------------------------------Mg + CuSO4 Cu + MgSO4Hypothesis==========The Magnesium will displace the Copper and rise in temperature becauseit is more reactive and it is an exothermic reaction.Results======= induct Temperature 22CEnd Temperature 28CRise In Temperature 6CThis preliminary experiment was very useful because it is aut horise thatthere was a very small rise in temperature. This fucking be solved byusing the pulverisationed form of metal, that can be used to increase the emerge area.Main Experiment================Correlating Zinc and Copper Sulphate Solution=============================================Prediction==========I address that the zinc will displace the copper to become zincsulphate.---------------------------------------------------------------Zinc + Copper Sulphate Zinc Sulphate + CopperI predict that the copper sulphate will only partially be heatedduring 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 zincribbon.I predict that the more zinc added to this reaction, the more thetemperature would become up to a true point.I predict that the temperature will increase when adding more z incuntil a certain mass of zinc is reached. If more zinc is added whenthe peak has been reached, therefore the temperature will decrease.Hypothesis==========The copper will be displaced because zinc is high 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 given take 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 oftenproducing less heat. Any more zinc would leave excess amounts, whichwould be harder to heat up and will reduce temperatures.
