From the developer:
HySS is a program that can be used to perform 2 distinct functions.
Titration simulation. A model is specified by defining a set of equilibrium constants
bpq.. = [ApBq..]/([A]p[[B]q..)
A titration is simulated by specifying a set of titration conditions and calculating the concentrations of each complex species as the titration proceeds. The results are shown graphically.
Calculation of species' concentrations.
