Acid-base equilibria, pH and titration
A pH Calculator, a Virtual Titrator, a Actual Titration Data Analyzer, a Distribution Diagram Power generator - thats CurTiPot, the all-in-one freeware to understand, educate and work with chemical equilibrium of acids, bases, salts and buffers at home, classroom, interactive "dry lab" or study laboratory. Features of this powerful collection of MS Excel spreadsheets take hold of:
- pH calculation of any aqueous answer of strong and poor acids, bases, salts, buffers and mixtures of up to 7 polyprotic systems (>40 varieties), with exercise coefficient evaluation;
- Simulation and overlay of acid-base titration curves of any difficulty, with or without random errors in pH and/or volume. Handy for teaching, generation of unlimited titration exercises and evaluation of the feasibility and accuracy of fresh titrations.
- Analysis of pH vs. volume data from simulated and actual potentiometric titration curves by two methods: i) graphical portrayal of curves, aided by cubic splines interpolation and smoothing of derivative curves, for accurate evaluation of inflections (end-points); ii) dedication of concentrations and refinement of pKa ideals by multiple nonlinear regression (centered on the Solver product of Excel), essential for hard titrations with undefined inflections, at the.gary the gadget guy., acid rain.
- Generation of protonation curves and distribution diagrams of equilibrium varieties of acids and bases at equilibrium as a function of pH or of added volume of titrant.
- Expandable data source with pKa ideals of 250 acids and bases.
Basically unzip the curtipot_.xls document, open up it with Microsoft Excel (at moderate security degree), activate macros and begin learning, operating and training. No install/uninstall needed, all macros are usually eliminated when shutting document. The software program is totally free of charge for academic and non-commercial make use of.
