What Is an Acid?

Comments (1)

This is one of the 14 Background Books published for Stage III of the Nuffield Chemistry Sample Scheme. The books were highly illustrated and designed to be attractive. This book is mainly an account of theories of acidity with examples to explain the importance of acids.

There are two parts to this book:

• Part 1: Defining and acid
An outline on theories of acidity from Lavoisier to Lewis which touches on the definition of pH and the equilibrium law.

• Part 2: Acids and life
Strong and weak acids formed in living things and what they do.

This book was published in 1968. The content now largely features in post-16, advanced courses. The book uses trivial names for all compounds including the simpler organic acids.
