2. Calculate the potential of the copper electrode immersed in a. 0.0440 M Cu(NO3)2 b. 0.0750 M in NaCI and sat'd with CuCı 3. Titration of 0.1756 g primary standard Na;C204 required 32.04 mL of a potassium permanganate solution. Calculate the molar concentration of KMNO4 in this solution. 4. a. Calculate the E° for the process AgIO:(s) + e° + Ag(s) + 103 b. Use the shorthand notation to describe the cell consisting of a saturated calomel reference electrode and a silver indicator electrode that could be used to measure plO3. c. Develop an equation that relates the potential of the cell in (b) to plO3. d. Calculate plo, if the cell in (b) has a potential of 0.294V. 5. A 0.1278-g sample of primary standard Na;C2O4 required exactly 60.04 mL of permanganate solution to reach the end point. What is the molarity of the KMNO4 reagent?
