ab: Summary: This article examines the symbolic algebraic solution of the
titration equations for a diprotic acid, as obtained using Mathematica,
Maple, and Mathcad. The equilibrium and conservation equations are
solved symbolically by the programs to eliminate the approximations
that normally would be performed by the student. Of the three programs,
Maple performs the best in terms of precision and speed. Mathcad is
unable to arrive at a symbolic solution for the system of equations as
posed. Mathematica can solve the algebraic problem, but requires
additional programming effort to handle instabilities that arise during
the calculation of numerical output.
