Redox Reactions

A cut apple turns brown, iron rusts, a battery runs, and food gives your body energy. All of these are reactions in which electrons move from one substance to another. In this chapter you learn to follow the electrons with oxidation numbers, name what is oxidised and what is reduced, balance difficult equations, and see how a redox reaction can drive a cell. Python balances equations and finds oxidation numbers for you.

Oxidation Numbers and Redox Reactions

Oxidation and reduction as the gain and loss of oxygen, hydrogen and electrons. The rules for oxidation numbers, oxidising and reducing agents, and the kinds of redox reaction, including disproportionation.

Not started 2.

Balancing Redox Equations and Titrations

Balancing by the oxidation number method and by the half-reaction method, in acidic and in basic solution. Then redox titrations with permanganate and dichromate, and how to find their results.

Redox and Electrode Potentials

A redox reaction split into two half-cells. The Daniell cell, standard electrode potentials and the electrochemical series. Then how to predict whether a reaction will happen and which metals displace which.
