#1. Molecules and their Interaction Relevant to Biology
  1. allows the graphic determination of the molecular weight of a weak acid from its pH alone.

  2. is equally useful with solutions of acetic acid and of hydrochloric acid.

  3. relates the pH of a solution to the pKa and the concentrations of acid and conjugate base.

  4. does not explain the behavior of di- or tri-basic weak acids
