Acid-Base Equlibria

Solving an acid base problem - S. E. VanBramer, Widener University, USA.
This tutorial focusses on identifying all the species in an aqueous solution and determining whether these species react as a prerequisite to calculations. In other words, you need to know what you have in solution in order to solve the problem. This is an excellent tutorial.
pH Titration Curves Download (This is a self-extracting archive)
Download a program which allows you to generate and explore pH titration curves exactly as you would in the laboratory. Unknowns with answers are provided.

Download the file to a temporary directory, c:\temp for example (NOT THE ROOT), and run the curv_arc.exe file. It will unfold into several files in the current directory. Run CURV.EXE to start the program.

pH Titration Curves Download (Spreadsheet)
To download a worksheet, hold down the shift key and click on pH Titration Curves Download. The worksheet allows you to generate titration curves for the strong acid/strong base case and any number of weak acid/strong base curves as a function of Ka as illustrated below. Instructions are provided. Worksheets are provided for Quattro Pro(".wb#"), Excel(".xls"), and Lotus(".wk#").

Download the file to a temporary directory, c:\temp for example (NOT THE ROOT), and run the ph_curve.exe file. It will provide the worksheet files which can be used with your spreadsheet program.
