CHEM 1E03 TUTORIAL #10 ____________________________________________________________________ Page 1 1. Use the E o red table (see next page) to answer the following problems. a) Calculate the standard cell potential, E o cell , for: Sn(s) + Cu 2+ (aq) Sn 2+ (aq) + Cu(s) b) Decide whether Cl 2 (g) (bubbled through an acid solution) will oxidize Mn 2+ (aq) to MnO 4 - (aq) under standard conditions. 2. Using the E o red table (see next page), select a suitable substance for each of the following transformations (assume that all soluble substances are present in 1.00 M concentrations): a) a reducing agent capable of reducing Ag + to Ag but not Cu 2+ to Cu. b) an oxidizing agent capable of oxidizing Co to Co 2+ but not Pb to Pb 2+ . 3. An electrochemical cell is made up of two half-cells, one consisting of a silver electrode dipping into a solution of 1.00 M AgNO 3 , and the other having a gold electrode in a 1.00 M solution of Au(NO 3 ) 3 . a) Write a balanced equation for the spontaneous cell reaction. b) Cell diagram using the shorthand notation c) Calculate the cell voltage. d) Do the electrons in the external circuit flow from Ag to Au, or from Au to Ag?

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
