pH is a simple little application to display pH curves for the titration of mono-, di-, and tri-protic acids against a strong base. The dissociation constant(s), concentration, and volumes to be used are entered, and then the graph may be plotted.


Installation

For a new installation, simply drag and drop the pH application into the directory of your choice.

If you have a previous copy of pH and you are updating, you should move the old version somewhere safe and replace it with the new version. Once you are satisfied with the operation of the new version, then the earlier version can be deleted.


Basic operation

To run the application, double click on it's icon in a filer window. This will load pH onto the iconbar.

Clicking on the iconbar icon with Select (or using the iconbar icon menu) will open the dialogue for input of starting details.


In these notes the left mouse button is referred to as Select, the right button as Adjust, and the center button as Menu.
