This lab was completed earlier this summer I am doing a review of the issues I had in lab last semester before classes start again. I Left the final 3 columns blank as I really didn't get it. . (12) In Part I of the procedure, you measured the cell potential for a variety of combinations ofhalf cells. Use a standard reduction potential table in your textbook to calculate the expectedEᵒcell using the formula Eºcell = Eºcathode - - E°anode. Calculate Eºcell for each combinationof cells. Show work for one calculation here, but you can enter the values in the table on page6.M = 0.581S 8.9910005.8110058.99Actual concentration of conce١٨ ٥٠٠ من one لسورMam-00980.098 but the Electrode 1CuCuCuCuZnZnZnPbPbElectrode 2MgZnPbMgSnPbMgSnMgSnCellpotentialEcell in VSnAnode0.976 ZnCaiоных трь си10 480Xси0mg•363 S Cu515 2nрь2n692 Ma482 2n10/21Cathode16-17pb1113 Ma ShEcell = Ecathode - E anodeMaBoSpрьSubstanceOxidized =Reducing OxidizingAgentAgentCu+2Zn+2Cut PbCutz MaCutz Sn+2Pb422n+2+2Sn+2Pb ¹²SubstanceReduced=mg2nMg2nmg+2Sn2 Pb+2SnPostlab #1:EᵒcathodePostlab #1:E anodePostlab #1:Eºcell

Halide ions can he deposited at a silver anode, the reaction being Ag(s) + X- AgX(s) +e- Suppose that a cell was formed by immersing a silver anode in an analyte solution that was 0.0250 M Cl-,Br-, and I -ions and connecting the half-cell to a saturated calomel cathode via a salt bridge. (a) Which halide would form first and at what potential? Is the cell galvanic or electrolytic? (b) Could I- and Br- be separated quantitatively?

A galvanic cell is based on the following half-reactions: In this cell, the copper compartment contains a copper electrode and [Cu2+] = 1.00 M, and the vanadium compartment contains a vanadium electrode and V2+ at an unknown concentration. The compartment containing the vanadium (1.00 L of solution) was titrated with 0.0800 M H2EDTA2, resulting in the reaction H2EDTA2(aq)+V2+(aq)VEDTA2(aq)+2H+(aq)K=? The potential of the cell was monitored to determine the stoichiometric point for the process, which occurred at a volume of 500.0 mL H2EDTA2 solution added. At the stoichiometric point, was observed to be 1 .98 V. The solution was buffered at a pH of 10.00. a. Calculate before the titration was carried out. b. Calculate the value of the equilibrium constant, K, for the titration reaction. c. Calculate at the halfway point in the titration.
