Questions to Answer in Your Report.

Please do not write your report as a set of answers to the following questions. Instead, use these questions for guidance of what important points should not be missed in presenting your results and discussion

• Make a plot of cathodic and anodic peak current vs. square root of scan rate for Fe(CN)₆^3- and Fe³⁺. Do you obtain the relashionship between i_p and n as you expected? Is it the same for both ions?
• Are the redox reactions that you observe all reversible? If not, what do you think happens?
• Report your numbers of E_1/2 for all species studied. Right the appropriate redox reactions. Any comments on how E_1/2 values vary between species? When report your numbers, make sure that you mention the reference electrode. It is also important to notice when you compare your results with reported data. By the way, you will need the numbers that you measure in one of your future labs.
• Were you able to record E_1/2 for O₂ + e^- --> O₂-? Elaborate on that.
• Evaluate accuracy of your measurements

c) Your own project.

You can come up with your own project within the scope of the setup you use.
