Electrochemistry

In this research project you will be studying various aspects of electrochemistry. You will be evaluated on the assignment questions (35%), a cumulative test (30%), a lab (part of the course lab grade) and your research paper (35%).

You are expected to use your textbook as your primary resource for this assignment (chapters 9 & 10). There are plenty of other chemistry textbooks available in class. The internet is not recommended as your primary resource since you do not know nearly enough about the topic to discern if the information is accurate or not. If you wish to use the internet to check your understanding or give you a basis for further book-study. Use sites ending in .edu as they are required to report accurate information. Any other sites should be checked for validity - i.e. see if the information can be backed-up in a book or other websites.

The questions follow the textbook from the beginning of chapter 9 to the end of chapter 10. It is recommended that you read the entire chapter, making your own notes and asking appropriate questions before attempting the questions.

You will be given 2 lessons on the subject, 1 day for preparing/research and 1 day for the laboratory. One lesson will be used as an instructional period while the other will be formatted by need (i.e. could be question and answer, instructional, time to work, etc.). The preparation can be scheduled for the library but it needs to be decided on in advance so I can book it for "you" as a class.

By then end of this IRP you should have an understanding of REDOX reactions & half-cells and understand both galvanic cells to electrolytic cells. You should also be able to calculate standard cell potentials as well as use half-cell for stoichiometry. Finally, you will research a topic related to electrochemistry and research the chemistry behind it. This must be done in groups of 2 or 3. There are 10 topics given but you may come up with your own topic as long as you get the "OK" from Mr. Taylor.

The due date for the questions is: April 18, 2011

The due date of the test is: May 11, 2011

The due date of the WikiPage is: April 26, 2011

The due date of the lab is: MOVED. Replaced with Electroplating (brought to you by the electroplating group!)

Wiki Assignment

The written assignment is a typical research paper with a chemical focus. This means that while you will be reporting on the topic as a whole, i.e. the chemistry first but also the social, economic & environmental issues, etc. Still, be sure to skew the paper towards explaining chemistry's role as this is a chemistry class! This means I expect you to explain the chemical procedures (in reasonable depth) and then explain their relationship to the other factors mentioned above. The wiki must be properly referenced and be equivalent to about a 5 page written paper. Topic suggestions are given below.


1. Hydrogen Fuel Cell
2. Plastic Battery
3. Electric Car
4. Solar Panels
5. Bio-fuels
6. Rechargeable Batteries
7. Alkaline Batteries
8. Wet Cell Batteries
9. Electroplating
10.Semiconductors and Superconductors
