298.15 K as a function of pH at ionic strengths of 0, 0.10, and 0.25 M (see
Problem 4.5).
As a test of the values of the thermodynamic properties that can be calculated
using BasicBiochemData2, it has been used to calculate the apparent equilibrium
constants at 298.15 K at the experimental pH and ionic strength of a number of
reactions in the critical compilations of Goldberg and Tewari (Goldberg et al.,
1992; Goldberg and Tewari, 1994a,b, 1995a,b; Goldberg, 1999). The table in
Problem 4.7 is a first step toward identifying errors in BasicBiochemData2. Since
the values of A,Go for species can be obtained from the existing data in different
ways, this redundancy can be used to find errors in experimental measurements
of K' and in the calculations to produce a thermodynamic database.
