Lesson: Oxidation Numbers Chemistry

In this lesson, we will learn how to calculate and use oxidation numbers.

Lesson Plan

Students will be able to

calculate the oxidation numbers of elements in compounds and ions,
describe changes in oxidation numbers in terms of the oxidation and reduction occurring within a chemical reaction,
identify a redox reaction through the change of oxidation number,
understand the relevance of redox reactions to oxidation states,
describe disproportionation.

Q1:

Give the oxidation state of chlorine in .

Q2:

What is the sum of the oxidation numbers of sulfur in the following chemical species: , and ?

Q3:

What is the oxidation number of oxygen in hydrogen peroxide?
