TitraSim is a Win32 program for computing
pH-values and acid-base titration curves for
systems where an arbitrary number of acids and/or
bases may be involved in both sample and
titrator. The program comes with archives
containing the most common acids/bases and their
pK-values. These archives can be extended by
adding new species or data referring to other
solvent systems or to non-standard temperatures.
Simulating the theoretical titration curves for a
mixture of such species is therefore a matter of
a few mouse clicks. Real experimental titration
curves (stored as volume/pH-value couples in
ASCII-files) can be imported into TitraSim and
compared with simulated ones. The determination
of analytical species concentrations and/or
pK-values can be accomplished in this way either
by "trial and error" (TitraSim - Standard) or by
making use of the non-linear fitting procedure
implemented into TitraSim - Professional.
