Unit 16: Oxidation-Reduction
Guiding Questions:
- How do batteries work?
- What makes a battery rechargeable?
- What makes rechargeable batteries "less rechargeable" after awhile?
- What is the difference between all the kinds of batteries?
What you should learn:
- Energy is transferred and a chemical change results when electrons move from one atom to another.
- Controlling the movement of electrons allows one to do useful work (e.g. electricity).
- Chemical potential energy can take a variety of forms.
More Specifically...:
- Electrochemistry
- Identify oxidation/reduction reaction using change in oxidation state
- Write half equations for oxidation and reduction
- Identify the species oxidized or reduced in a redox reaction
- Identify the oxidizing agent and reducing agent
- Balance redox reactions using
- a. Oxidation state
- b. Half reactions
- Write complete ionic equations, net ionic equations, and identify spectator ions
- Write redox reactions using cell notation
- Define standard electrode potential and describe how they are measured
- Describe how a simple battery (cell) provides electricity
- Define electrolysis
- List applications of oxidation/reduction reactions
- Math
- Calculate cell potentials and determine the spontaneity of redox reactions
