  1. OH- + HF ----> H2O + F-
    OH- is base
    HF is acid
    H2O is neither
    F- is base

    acid + base gives base + water

  2. Note that in the Bronsted-Lowry theory that
    the OH^- is a base and H2O is a conjugate acid.
    HF is an acid and F^- is a conjugate base
    In the B-L theory an acid gives up a H^+ to produce a conjugate base and a base adds a H^+ to form a conjugate acid.
    H2SO4 is an acid and HSO4^- is the conjugate base but in other reactions HSO4^- is an acid and SO4^2- is the conjugate base.
