Oxidation b. Reduction c. Oxidizing Agent d. Reducing Agent e. Anode f. Cathode g. Salt Bridge 2. Fill in the chart below regarding voltaic and electrolytic cells. Voltaic Electrolytic Utilizes what type of reactions? The more active metal is… The anode has what charge? The cathode has what charge? Electrons flow from… Uses/produces energy? 3. What are the three main uses of electrolytic cells? 4. What is electroplating? Label the anode, the cathode and the flow of electrons. Assign charges to the anode and the cathode. What material is being oxidized? Reduced? 5. How is location on the activity series (Table J) used to determine the spontaneity of a redox

Unformatted text preview: reaction? Assign a redox reaction to the relative location of the metals. Which metal will always be oxidized? Which metal will always be reduced? 6. Assign oxidation states, write the redox half-reactions, and label the oxidizing and reducing agent. a. Fe + CuSO 4 Cu + Fe 2 (SO 4 ) 3 b. Co + KMnO 4 CoO + KMnO 3 c. 2 H 2 + O 2 2 H 2 O 7. Draw a voltaic cell using Ag (s)/Ag + (aq) and Mg(s)/Mg 2+ (aq) as your electrodes and electrolytic solutions. Be sure to label: Anode and cathode (with charge) Flow of electrons Salt bridge Where oxidation occurs (and half reaction) Where reduction occurs (and half reaction) Provide the complete, balanced redox equation Calculate the voltage of the cell 8.
