Reduction and oxidation or ‘redox’ reactions take us down an important conceptual pathway in chemistry as they allow us to understand that all chemical reactions can be perceived as the rearrangement of electrons. In this course you will gain a greater understanding of the key concepts in redox reactions and how to support your students in their learning. These concepts include what is meant by redox reactions; how an ‘order of reactivity’ for a reaction is determined by comparing the reactivity of the ions present in a reaction; what electrode potentials are and how they can be used to predict the feasibility of redox reactions.
