phtitration - Version 1.0.0

phtitration is a LaTeX package 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.
• Built-in geometric macros to automatically draw the tangent method (méthode des tangentes) at equivalence points.
• Highly customizable coordinates, labels, units, and plot styling.

Installation

Put phtitration.sty in your working directory or in your local texmf tree. For TeXstudio users, a .cwl file is provided for auto-completion.

Documentation

Please refer to phtitration-doc.pdf for a comprehensive manual and usage examples.
