Electrochemical Changes
1. How can you differentiate between redox reactions and other reactions, using either half-reactions and/or oxidation numbers?
2. What are the relative strengths of various oxidizing and reducing agents and how do they compare?
3. Based on standard reduction potentials, predict the spontaneity of a redox reaction.
4. What are the oxidizing agent, reducing agents and electron transfer in some of the more common everyday redox reactions (eg. Cellular respiration, photosynthesis, corrosion)?
5. How do voltaic and electrolytic cells compare?
6. What are the half-reaction equations that occur at each electrode in a given electrochemical cell?
7. How are the standard cell potentials for electrochemical cells calculated?
8. Using standard cell potential and the relative positions of half-reaction equations on a standard reduction potential table, is the redox reaction spontaneous or nonspontaneous?
9. Using Faraday’s law and stoichiometry, what is the mass, amount, current and/or time in a single voltaic and electrolytic cell?
