CurTiPot pH & Acid-Base Titration Curves is a a free software implemented into a .xls file for simulation and analysis of Potentiometric Titration Curves and for pH and acid-base equilibrium calculations.

Here are some key features of "CurTiPot pH Acid Base Titration Curves":

  • pH calculations - from simple solutions to complex mixtures (>30 species) of acids, bases and salts in aqueous medium, including buffer solutions;

  • pH vs. volume of titrant data analysis of simulated and real potentiometric titration curves:
    » graphical representation of curves, derivatives and distribution of species;
    » precise evaluation of inflections of the curves by interpolation and smoothing of derivative curves with cubic splines;
    » determination of multiple concentrations and refinement of pK values by nonlinear regression; decisive for very diluted, complex samples and other titrations with undefined inflections, eg., acid rain.

  • Simulation of acid-base titration curves;
    » data generation of simple and complex mixtures of acids and bases (>30 species) in aqueous solution;
    » simulation of data with random experimental errors in pH and/or volume with Gaussian distribution;
    » overlay of curves (>10) for visualization of the effect of changing parameters;
    » preparation of an unlimited number of different titration curves for students' examinations.

  • Generation of protonation diagrams and distribution curves of the equilibrium species of acids and bases as a function of pH as well as vs. volume of titrant.

    Limitations
  • Ionic strength and activity coefficient calculation not yet implemented in Excel
  • Protonation-desprotonation is considered instantaneous and no other type of reaction or phase transition is taken in account.
  • For Regression, pH values are assumed as free of calibration, junction
