Acid dissociation constants, for

Lide, D. R., Ed. (2003). CRC Handbook of Chemistry and Physics, 84th ed. CRC Press, Boca Raton, FL. Extensive tables of dissociation constants for acids and bases are available in this handbook. 

Khodakovskiy (16) used this assumption to extrapolate dissociation constants for acids, Henry s law constants for gases and solubility products for salts. In a variation of this technique Khodakovskiy (17) has extrapolated partial molal heat capacities of ions and neutral molecules by using C = bT. 

In theory, any electrode system in which hydrogen ions are participants can be used to evaluate dissociation constants for acids and bases. 

This procedure of expressing the acids as oxo-hydroxo complexes of water is in full agreement with the corresponding reactions occurring with, e.g., the transition metal cations in aqueous solutions. Table 8.5 provides the dissociation constants for acids expressed in this unconventional way. °... 

Available from Pharmacia Biotech as Immobiline, these are "derivatives of acrylamide with different dissociation constants. For acidic Immobiline (with pK 3.6 or 4.6), carboxylic acid is chosen as a functional group for the bases, tertiary amino groups are selected. When different pK values of Immobiline are mixed in appropriate proportions, together with acrylamide, bisacrylamide, TEMED, and ammonium persulfate, the buffering groups responsible for ereating the pH gradient become covalently attached to the polyacrylamide base.

The stability constant given in Eq. 4 is an association constant. A dissociation constant is numerically equal to the reciprocal of the corresponding association constant. It is common practice to quote dissociation constants for acids (particularly organic acids), while association constants are used for complexes. For a monobasic acid, HL. there are no further complications. But for polybasic acids, the numerical order of the two sets is reversed. For example, for a dibasic acid, the first stepwise dissociation constant is equal to the reciprocal of the second stepwise association constant and vice versa.
