Textbook Question
Chapter 19, Problem 19.38P
8 In Chapter 22, we will discuss a class of compounds called amino acids, so named because they contain both an amino group and a carboxyl group. Following is a structural formula for the amino
acid alanine.
What would you expect to be the major form of alanine present in aqueous solution (a) at pH 2.0, (b) at pH 5—6, and (c) at pH 11.0? Explain.

The antimalaria properties of quinine (C20H24N202) saved thousands of lives
during construction of the Panama Canal. This substance is a classic example of
the medicinal wealth that tropical forests hold. Both N atoms are basic, and the
N of the amine group is far more basic (pKb=4.94) than the N within the
aromatic ring system (pKb=10.54). A saturated solution of quinine in water is
only 4.55x10-3M. What is the pH of this solution? Record your answer with 2
decimals.
