    Acid and Base Definitions

    ACID H+ donor e- acceptor
    BASE H+ acceptor e- donor
    bronsted acids and bronsted bases

    Characteristics of Acids and Bases

    ↑Ka = stronger acid, ↑Kb = stronger base

    ↓pKa = stronger acid, ↓pKb = stronger base

    The stronger the acid, the weaker its conjugate base.

    The more stable the base, the weaker the base.
