Electrochemical cell lab Aim Essay

Aim - To find out the feasibility of a redox reaction by looking at the cell potential of the reaction .Quantitative observationThe table below shows the values of cell potential that were recorded when the experiment was performed answerCell potential (0.01V)CuSO4 and ZnSO40.99VCuSO4 and AgNO30.64VAg1.39VQualitative ObservationReactionObsevrationsCuSO4 and ZnSO4 bulls eye sulphate turns from clear to blue , whereas zinc sulphate remains colorlessCuSO4 and AgNO3Copper sulphate is blue in color , silver nitrate is colorlessAgData processingExperiment 1Zn(s) - Zn2+ (aq) + 2e- (aq)Cu2+ (aq) + 2e- (aq) - Cu (s)Cu2+ (aq) + Zn(s) - Cu(s) + Zn2+ (aq)Experiment 2Cu(s) - Cu2+ (aq)+ 2e- (aq)Ag+(aq) + e- (aq) - Ag(s)Cu(s) + 2Ag+ (aq) - Cu2+ (Aq) + 2Ag (s)Experiment 3Zn(s) - Zn2+ (aq) + 2e- (aq)Ag+ (aq) + e- (aq)- Ag(s)Zn(s) + 2Ag+ (aq) - Zn2+ (aq) + 2Ag (s)The table below shows the literature values for the respective cell potentialReactionCell potential (0.01V)CuSO4 and ZnSO40.34VCuSO4 and AgN O30.46 V.Ag1.10 VError percentage= (difference between the literature and experimental value)/(the literature value )x100= (0.34V 0.99V)/(0.34V) x100= 191.17%We can similarly find the error percentages for different cell potentials alsoThe table below shows the respective error percentages of each of the cell potentialReactionError percentageCuSO4 and ZnSO4191.17%CuSO4 and AgNO339.13%Ag16.36%Theoryelectrochemical cellsIn an electrochemical cell, electricity is produced through chemical reactions. There consist two electrodes the negative electrode and the positive electrode. At the negative electrode
