phtitration – Draw highly accurate pH titration curves using TikZ and pgfplots

This LaTeX package has been designed for rendering highly accurate pH-metric titration curves using TikZ and pgfplots. By employing exact mass and charge balance equations via parametric plotting, it ensures perfectly smooth, continuous curves without the visual breaks typical of piecewise Henderson-Hasselbalch approximations.

Features:

• Supports 8 standard acid-base titration configurations (including mono-, di-, and triprotic acids/bases).
• Built-in geometric macros to automatically draw the tangent method at equivalence points.
• Highly customizable coordinates, labels, units, and plot styling.
