About CurTiPot, A pH calculator, a virtual titrator, a real titration data analyzer, a distribution diagram generator and a pKa database built into a single freeware boosted by chemometric tools for simulation, interpolation, smoothing and multiple nonlinear regression - that's CurTiPot. No install/uninstall or registration hassle; simply open the curtipot_.xls file, activate macros and start learning, working and teaching. Compute the pH of aqueous solutions of any single acid or base (strong, weak, mono or polyprotic), amino acids, buffers and complex mixtures. Simulate their titration curves. Improve the accuracy of the evaluation of real experimental data from potentiometric titrations and consider samples ranging from vinegar, wine, and juices to humic acids and acid rain.
