Chemist
Chemist is a program for chemical equilibrium calculations. The program uses a simple Windows interface
where you specify the compounds and their quantities that make up the solution of interest. These
compounds are selected from a large database provided with the program and the quantities can be entered
in many of units of either mass or concentration. Once the solution has been entered, you simply
press a "solve" button and the program will perform the calculations and display the results in a
spreadsheet. These results include molar concentrations and activity coefficients for all species
in the solution, as well as pH, ionic strength, buffer capacity and estimated density.
Chemist will also indicate the degree of saturation of the solution with respect to any solids that could
potentially be formed. Multiple conditions can be done in one calculation. In addition, the results of
titration calculations can be displayed and printed as plots. The program comes with a database of
compounds which has 500 chemical equilibrium relationships that are automatically included in the calculations
as needed. If you've ever had to work out and solve the algebra behind these calculations, you will
appreciate the hours of tedious and unrewarding work that Chemist will save you. And for those of you
in the lab, you can save days of work by performing pertinent "whatif" calculations instead of running
expensive trialanderror laboratory experiments.
