Learning Objectives

By the end of this section, you will be able to:

Predict whether a salt solution will be acidic, basic, or neutral

Calculate the concentrations of the various species in a salt solution

Describe the process that causes solutions of certain metal ions to be acidic

As we have seen in the section on chemical reactions, when an acid and base are mixed, they undergo a neutralization reaction. The word “neutralization” seems to imply that a stoichiometrically equivalent solution of an acid and a base would be neutral. This is sometimes true, but the salts that are formed in these reactions may have acidic or basic properties of their own, as we shall now see.
