Ionic Strength Corrections for Stability Constants
IUPAC has approved a three-year project to produce a freely available
computer program to correct activity coefficients and, hence, stability
constants, for ionic strength changes over a wide range of molalities.
Calculations will be based on Specific Interaction Theory (SIT).
The program will contain a small database of interaction coefficients
for many common ions and media (not critically evaluated) and facilities
for calculating approximate values when experimental values have not
been reported in the literature. It will be possible for users to add
new values to the database, or to correct existing values.
Comments from the chemistry community are welcome and should be addressed
