BATE
	BATE calculates pH of solutions containing mixtures of acid and base with up to 4 dissociation steps and titration curves for these acids and bases. Ionic strentgh can be calculated from the dissociated forms concentrations, omitted or forced upon the solution. Program contains editable database of common weak acids and bases and accepts acid and base dissociation constants and protonation constants as input, calculating all other types of constants as needed. Built in calculator allows easy calculation of molar masses and concentrations for a given substance formula. Printouts describing equlibrium contain information of concentrations and activties of all ions present in the solution, together with activity coefficients (if applicable). Titration printouts contain titration curves for both titrations (acid/base and base/acid) and pH of all end points. Extensive tutorial and help. Very low hardware requirements - if your Windows start, BATE will work.

	CurTiPot Acid-Base pH and Titration
	CurTiPot is a powerful all-in-one freeware for acid-base equilibria calculations such as pH of aqueous solutions, dissociation degree of weak and polyprotic systems, pKa determinations, simulation of titration curves and analysis of real titration data with chemometric tools like interpolation, smoothing and regression. The program is free of charge for noncommercial personal, classroom (high school and college), laboratory and research use and provides: - pH calculations of strong, weak an multiprotic acids, bases, salts and their buffers and mixtures (up to 30 species at once) in aqueous medium; - Analysis of pH vs. volume of titrant data of 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, for example, acid rain. - Simulation and overlay of acid-base titration curves of any complexity, without or with simulated random experimental error in pH and/or volume. Valuable for teaching, generation of unlimited titration exercises and evaluation of the feasibility and accuracy of new titrations. - Generation of protonation diagrams and distribution curves of the equilibrium species of acids and bases as a function of pH or of added volume of titrant. All necessary spreadsheets with graphics, examples, instructions, database and visual basic macros are contained in the single curtipot_.xls file. Simply unzip, open with Microsoft Excel (at medium security level), activate macros and start learning and working. No install/uninstall required, all macros are removed when closing file. The 1992 CurTiPot for DOS (with activity coefficient calculation) runs in Windows without Excel. Company: Ivano G. R.
