A 0.2000gNaBr(102.8938g/mol) sample is weighed accurately and placed in a flask with 25.00mL of deionized water. You add the Ag electrode and a reference electrode and titrate the sample with 0.0950M AgNO3 to the potentiometric endpoint at 25C. AgBr(s)Ag+(aq)+Br(aq):Ksp=5.001013 Ag++1eAg;E0=0.799V SHE Answer the following: 1) What is the volume of the endpoint for the titration? (1 mark) 2) What is the potential of the endpoint in V vs SHE? (1 mark) marks). For full marks, please show detail just before and after the endpoint - as we did in the assignment 4A. I have opened a drop box (Midterm drop box) for you to paste your Excel spreadsheet. The titrate.xls spreadsheet is not necessary
