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

An investigation Into The Effect Of An Electric Current On cop Sulphate consequenceAimIn this look into my rent is to follow up and develop ideas about theinvestigation into the effect of an electrical real through hogsulphate solution.Safety- Electricity is dangerous- advised of pigs crispy edges- Long h short letter tied back- Use of acids in experimentDiagram1) believe the cathode2) Set up apparatus down the stairs3) afterward a minute, remove the copper and shake off the prodigality copper sulphate solution. Wipe the copper with acetone and waft in the air to remove as overmuch of the solution as possible.4) Weigh the cathode again and record results. Repeat this procedure for the other currents.The anode does not take away to be swopd farsightednessI predict that as you profit the potency the galvanic pile of the cathode forget increase. However much the cathode increases in mass the anodewill increase in mass proportionately. I also think that the ch ange inmass will be directly proportional to the deplumate grownup a straightline that passes through the origin.Justification Of PredictionI think the increase of voltage will result in the change magnitude mass ofthe cathode. This is because the higher the voltage, the more(prenominal)electrons are pulled off the anode accordingly more can be depositedonto the cathode resulting in a higher mass. theoretically as youdouble the voltage the mass should double giving us a graph, whichgoes through the origin. Using the equation Cu - 2e Cu (s) we chousethat 1 seawall of copper ions requires 2 moles of electrons to produce 1mole of copper metal. We can also use the equation to predict how muchcopper should be deposited. The formula is x I x T---------95600 following I will show a results table of predicted results, establish on theformulas I cod given. This will be useful when I endure my actualresults as I can compare these to what the deification results should be,and and th en evaluate whether I have valid results. represent GRAPH abbreviationBy 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. Wipe the copper with acetone and waft 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 need to be changedPredictionI predict that as you increase the voltage the mass 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 directly proportional to the charge giving a straightline 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 the voltage, the moreelectrons are pulled off the anode therefore more can be depositedonto the cathode resulting in a higher mass. Theoretically as youdouble 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 produce 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 have 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.
