    KaKb = Kw
    A stronger acid has a larger Ka / smaller pKa.
    A stronger base has a larger Kb / smaller pKb.
    The stronger the acid, the weaker the conjugate base.
    The stronger the base, the weaker the conjugate acid.

    What is the pH of a 0.1M solution of acetic acid (Ka = 1.76×10-5)?

    what is 01
    what is 02

    What is the Ka of a weak acid, HA, if the pH of a 0.1M solution is 3?
    What is the percent dissociation of this acid?

    What is the pH of a 0.1M solution of ammonia (Kb = 1.75×10-5)?

    What is the Kb of a weak base, A-, if the pH of a 0.1M solution is 10.2?
