![]() Simply unzip the curtipot_.xls file, open it with Microsoft Excel, enable macros and start learning, working and teaching. * Expandable database with pKa values of 250 acids and bases. * 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. 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. ![]() Valuable for teaching, generation of unlimited titration exercises and evaluation of the feasibility and accuracy of new titrations. ![]() * Simulation and overlay of acid-base titration curves of any complexity, with or without random errors in pH and/or volume. * pH calculation of any aqueous solution of strong and weak acids, bases, salts, buffers and mixtures of up to 7 polyprotic systems (>40 species), with buffer capacity and activity coefficient estimation Features of this powerful suite of MS Excel spreadsheets embrace: A pH Calculator, a Virtual Titrator, a Real Titration Data Analyzer, a Distribution Diagram Generator - thats CurTiPot, the all-in-one freeware to learn, teach and work with chemical equilibrium of acids, bases, salts and buffers at home, classroom, interactive "dry lab", routine or research laboratory.
