Summary description: Draw highly accurate pH titration curves using TikZ and pgfplots
Announcement text: ------------------------------------------------------------------------
I am pleased to announce the initial release (v1.0.0) of the phtitration package.
This package provides LaTeX macros to render highly accurate pH-metric titration curves using TikZ and pgfplots. By employing exact mass and charge balance parametric equations, it ensures smooth, continuous curves without the visual breaks typical of piecewise approximations.
Key features: - Supports 8 standard acid-base titration types (including polyprotic). - Automatically draws the tangent method (méthode des tangentes) at equivalence points. - Highly customizable styles, coordinate labels, and units.
Thank you!
