3. (15 points) Suppose a A1/A1³+ and Cu/Cu²+ voltaic cell is constructed with [Cu²+] = 0.5M and [A1³+] = 0.5M. Calculate the cell potential under these conditions (refer to Table 3). 4. (10 points) 1.5 g of Ag (107.87 g/mol) is deposited on a surface from a solution con- taining Ag+ ions. How long would it take a 1.0A power source to deposit this amount of Ag? 5. A voltaic cell is constructed based on the oxidation of zinc metal and reduction of silver cations. (I) (25 points) A voltaic cell is formed from 1.0M copper(II) nitrate and 1.0M alu- minum nitrate. Draw a picture of the voltaic cell. In your drawing, include the electrodes, aluminum metal, copper(II) nitrate, copper metal, aluminum nitrate, salt bridge, and identify the anode and the cathode (see standard reduction poten- tials in Table 3). Half-reaction Cu2+ (aq) + 2e Al³+ (aq) + 3e → Cu(s) Al(s) Standard Reduction Potential (V) +0.34 -1.66 Table 3:
