CurTiPot AcidBase pH and Titration
CurTiPot is a powerful all-in-one freeware for acid-base equilibria calculations such as ph of aqueous solutions, dissociationdegree of weak and polyprotic systems, pKa determinations, simulation of titration curves and analysis of real titration data with chemometrictools like interpolation, smoothing and regression... volume of titrant data of simulated and real potentiometric titration curves by two methods: i) graphical representation ofcurves, assisted by cubic splines interpolation and smoothing of derivative curves for accurate evaluation of inflections (end-points); ii)determination of concentrations and refinement of pKa values by multiple nonlinear regression (based on the Solver supplement of Excel),essential for difficult titrations with undefined inflections, for example, acid rain... Valuable for teaching, generation of unlimited titration exercises and evaluation of the feasibility and accuracy of new titrations...
