This chapter describes how redox reactions make possible energy interconversion between electrical energy and chemical energy. Voltaic and electrolytic cells are compared. The concept of oxidation and reduction half-cells is introduced as a means of calculating standard cell potentials and determining whether or not a redox reaction is spontaneous.

In this chapter, you will learn: to describe redox reactions to explain the structure of a dry cell to define standard cell potential and standard reduction potential to distinguish between electrolytic and voltaic cells to identify the products of electrolysis
