Volume data from simulated and real potentiometric titration curves by two methods: i) graphical representation of curves, 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, e.g., acid rain. * Generation of acid-base species distribution diagrams and curves of buffer capacity, protonation level and average charge as a function of pH and added volume of titrant, with isoelectric point detection. * Expandable database with pKa values of 250 acids and bases. ![]() Simply unzip the curtipot_.xls file, open it with Microsoft Excel, enable macros and start learning, working and teaching. ![]() No install/uninstall required, all macros are removed by closing the file.
