Name: _________________________________________ Date: ____________ WKST #24: Voltaic Cells (40 points) Period: ___________ 1. Why is the reaction Zn (s) + Cu 2+ (aq) Zn 2+ (aq) + Cu (s) spontaneous while the reaction Cu (s) + Zn 2+ (aq) Cu 2+ (aq) + Zn (s) is non-spontaneous? 2. Explain how to use Table J as a means of predicting the spontaneity of a redox reaction. 3. In a ______________________ cell, ____________________ redox reactions are used to produce electricity. The electrode where oxidation takes place is called the _________________ and has a __________ charge. The electrode where reduction takes place is called the ______________ and has a ____________ charge. The _________________ serves as a passageway for ions to travel back and forth between the reactions. 4. For each pair of metals below: Determine which would be the anode and which would be the cathode Write the half reaction for the oxidation and reduction reaction Write the complete, balanced redox reaction

Draw a voltaic cell using Ag (s)/Ag + (aq) and Al(s)/Al 3+ (aq) as your electrodes and electrolytic solutions. Be sure to label: Anode (with charge) Cathode (with charge) Flow of electrons Salt bridge Where oxidation occurs (and half reaction) Where reduction occurs (and half reaction) Full, balanced redox equation Calculate the voltage of the cell 6.
