Ch 13Supplemental InstructionIowa State UniversityLeader: LaurenCourse: Chem 167Instructor: HolmeDate: 12/06/091. What is a galvanic cell, and what are its components?2. a) What is an electrode? b) What is an anode? c) What is a cathode?3. Why is a salt bridge needed?4. In a galvanic cell, one electrode compartment consists of an aluminum strip placed in a solution of Al(NO3)2, and the other has a nickel strip placed in a solution of NiSO4. a) Write the overall cell reaction, using Appendix I to determine what is oxidized and what is reduced. How do you know? b) Draw the galvanic cell, labeling the anode and the cathode.Supplemental Instruction1060 Hixson-Lied Student Success Center v 294-6624 v www.si.iastate.edu5. What is meant by ‘standard state’ in terms of the electrochemical cell, and what is standard?6. These galvanic cells have a potential for electrical work, called the ________________ or the _______________________. What is the equation for this?7. Determine the E⁰cell from the reaction in number 4. 8. a) How does galvanic corrosion occur? b) How does uniform corrosion occur?9.
