    Properties of Weak Bases

    I'm so confused about this! My textbook seems to be contradicting itself. First it says that the conjugate bases of strong acids are weak bases, and vice versa, but then it says that some example of weak bases include the anions of WEAK acids. That doesn't make sense. Help!
