Chapter 7
Redox Reactions
Oxidation Number and Types of Redox Reactions, Balancing Redox Equations and Redox Titrations

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.
