Big Picture
Oxidation and reduction reactions are responsible for most of the life processes that provide energy for living systems. They also provide energy for non-living system and are used in various commercial and industrial processes. In this module we will learn more about redox reactions and the processes they are involved in.
Module 2 Inquiry
- What is reduction ?
- What is oxidation ?
- What processes rely on redox reactions ?
- How are redox reactions represented ?
Lesson 1.2.1
Lesson 1 - Compounds and Chemical Change
Get Focused
Predicting the chemical yields of chemical reactions requires a knowledge of the mole and molar ratio's. In this lesson we will review the concept of the mole and learn how to use molar ratios to predict chemical yields.
Consider the following essential questions as you complete Lesson 1:
- What is a mole ?
- What is a molar ratio ?
- What is a limiting reagent ?
- How do we calculate percent yield

Lesson Summary
In this lesson you learned about the mole, limiting reagents, and using mole ratio's to predict the amount of reactants and products that participate in chemical reactions.
Lesson 2 will look at the gain and loss of electrons of redox reactions.
Lesson 1.2.2
Lesson 2 - The Gain and Loss of Electrons
Get Focused
Electrons are shared or exchanged during chemical reactions. The re-positioning of electrons can either liberate or require energy. In this lesson we will investigate the gain and loss of electrons in redox reactions.
Consider the following essential questions as you complete Lesson 2:
- What is oxidation ?
- What is reduction ?
- Can a redox reaction have oxidation without reduction or vice versa ?
- What does the acronym LEO GER mean

Lesson 3 will look at the electrical reactivity of metals.
Lesson 1.2.3
Lesson 3 - The Reactivity of Metals
Get Focused
Redox reactions takes place according to the relative reactivity of the metals involved. In this lesson we will investigate how to order the reactivity of various metals and learn how this reactivity affects redox reactions.
Consider the following essential questions as you complete Lesson 3:
- What is reactivity ?
- How do you determine the relative reactivity of a metal ?
- How do you construct a conductivity table

Lesson 4 will look at the structure and function of a voltaic cell.
Lesson 1.2.4
Lesson 4 - Using Voltaic Cells
Get Focused
We use voltaic cells to operate a wide variety of portable electronic devices. In this lesson we will investigate the fundamental chemical principles behind the operation of voltaic cells and understand their operation.Consider the following essential questions as you complete Lesson 4:
- What is a spontaneous reaction?
- What is a galvanic cell ?
- How do you determine whether a redox reaction will be spontaneous or not ?
- What happens at the anode and cathode in a voltaic cell
