CurTiPot Acid-Base pH and Titration 3.4.1 Description

" CurTiPot Acid-Base pH and Titration : All-in-one freeware for pH and equilibrium calculations, real data analysis and simulation of titration curves of acids, bases, salts and buffers ( from simple solutions to complex mixtures ) with interpolation, smoothing and nonlinear regression. .. "

Editor: CurTiPot Acid-Base pH and Titration - A pH Calculator, a Virtual Titrator, a Real Titration Data Analyzer, a Distribution Diagram Generator-that' s 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. Features of this powerful suite of MS Excel spreadsheets embrace:
* 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 activity coefficient estimation;
* Simulation and overlay of acid-base titration curves of any complexity, with or without random errors in pH and / or volume. Valuable for teaching, generation of unlimited titration exercises and evaluation of the feasibility and accuracy of new titrations.
* Analysis of pH vs. 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 protonation curves and distribution diagrams of equilibrium species of acids and bases at equilibrium as a function of pH or of added volume of titrant.
* Expandable database with pKa values of 250 acids and bases.
