The antimalaria properties of quinine (C20H24N2O2) 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 °M. What is the pH of this solution? Record your answer with 2 decimals.

Question
Transcribed Image Text: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.
