Electrochemical cell lab Aim Essay

Aim - To fancy out the feasibility of a redox chemical reaction by looking at the cell capablenessity of the reaction .Quantitative observationThe table infra shows the values of cell likely that were recorded when the taste was performedReactionCell potential (0.01V)CuSO4 and ZnSO40.99VCuSO4 and AgNO30.64VAg1.39Vqualitative ObservationReactionObsevrationsCuSO4 and ZnSO4Copper sulphate turns from recognize to blue , whereas zinc sulphate remains paleCuSO4 and AgNO3Copper sulphate is blue in color in , silver nitrate is colorlessAgselective information processing examine 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 down the stairs shows the literary works values for the several(prenominal) cell potentialReactio nCell potential (0.01V)CuSO4 and ZnSO40.34VCuSO4 and AgNO30.46 V.Ag1.10 VError percentage= ( distinction 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 other 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% openingElectrochemical cellsIn an electrochemical cell, electricity is produced through chemical reactions. There consist two electrodes the invalidating electrode and the positive electrode. At the negative electrode
