All-in-one Freeware for pH and
Acid-Base Equilibrium Calculations,
and for Simulation and Analysis of entiometric Pot
Find the pH of any aqueous solution
Evaluate your acid-base titration curve data with enhanced speed and accuracy. Simply paste or introduce your pH vs. Volume data into the Evaluation or Regression spreadsheets
Make virtual titrations, compare real with simulated curves, practice visual end point detection and generate distribution diagrams of 250 acids and bases listed in the pKa database
CurTiPot requires no instalation or registration and is free for non-commercial use. It is compatible with Microsoft Excel
TM from 1997 onwards.

Dear Dr. Gutz,
I found your Curtipot program from the Buffer solution page on Wikipedia. I very much like it. I plan to use it in classroom demonstrations here at Rice University.
Great job on the program!

I have used your CurTiPot program, and find it very useful and powerful.

Curtipot - A spectacular acid-base titration spreadsheet
CHE 133 Syllabus and Shedule
Stony Brook University
...CurTiPot, a Microsoft Excel (Redmond, WA, USA) spreadsheet, presents particularly detailed information on ionization states and activity coefficients. It also simulates virtual acid–base titrations, and performs multiparametric nonlinear regression to recover concentrations and/or pKa's of multiple species from experimental titration data. ... Of these packages, we recommend CurTiPot for most acid–base problems, PeakMaster for simple electrophoresis problems where ion mobility and buffer conductivity are relevant; and Simul or Spresso for acid–base equilibria in full-scale electrophoresis simulations.
