    Acids and Bases: Use of the pKa Table - UCLA

    Acids and Bases: Use of the pK a Table. Discussion: The propensity of a compound to donate a proton is measured as its acid ionization constant, or K a.These K a values cover a wide range of 10 10 for the strongest acids such as sulfuric acid to 10-50 for the weakest acids such as methane. A more convenient scale of acidity is pK a which is the negative logarithm of the K a (pK a = -log K a).
