An Investigation Into The Effect Of An Electric Current On Copper Sulphate Solution :: GCSE Chemistry Coursework Investigation

An Investigation Into The Effect Of An galvanic Current On Copper Sulphate etymon objective lensIn this experiment my aim is to enforce and develop ideas about theinvestigation into the effect of an electrical current through coppersulphate solution. synthetic rubber- electrical energy is dangerous- Aware of coppers sharp edges- Long hair tied back- Use of acids in experimentDiagram1) Weigh the cathode2) Set up appliance below3) After a minute, remove the copper and shake off the excess copper sulphate solution. Wipe the copper with acetone and pennant in the air to remove as much of the solution as possible.4) Weigh the cathode again and record results. Repeat this procedure for the other currents.The anode does not enquire to be changedPredictionI predict that as you make up the voltage the great deal of the cathodewill increase. However much the cathode increases in mass the anodewill increase in mass proportionately. I also think that the change inmass will be direct ly proportional to the charge giving a solidline that passes through the origin.Justification Of PredictionI think the increase of voltage will result in the increased mass ofthe cathode. This is because the higher(prenominal) the voltage, the more thanelectrons are pulled off the anode therefore more can be depositedonto the cathode resulting in a higher mass. Theoretically as you iterate the voltage the mass should double giving us a graph, whichgoes through the origin. Using the equation Cu - 2e Cu (s) we knowthat 1 mole of copper ions requires 2 moles of electrons to baffle 1mole of copper metal. We can also use the equation to predict how muchcopper should be deposited. The formula is x I x T---------95600Next I will show a results table of predicted results, based on theformulas I start given. This will be useful when I have my actualresults as I can compare these to what the ideal results should be,and then evaluate whether I have valid results. GRAPH GRAPH abstractBy using the equation, Cu - 2e Cu (s) and the formula Q = I x T/ 95600 we can work out how much copper should have been deposited.An Investigation Into The Effect Of An Electric Current On Copper Sulphate Solution GCSE Chemistry Coursework InvestigationAn Investigation Into The Effect Of An Electric Current On Copper Sulphate SolutionAimIn this experiment my aim is to enforce and develop ideas about theinvestigation into the effect of an electrical current through coppersulphate solution.Safety- Electricity is dangerous- Aware of coppers sharp edges- Long hair tied back- Use of acids in experimentDiagram1) Weigh the cathode2) Set up apparatus below3) After a minute, remove the copper and shake off the excess copper sulphate solution.
