CompuChem Chemical Formula Tutor 
95-2000 ME+NT
Beginners in chemical courses often have problems in balancing chemical equations.
Now the new CFT helps by interactive PC-training.
Select any positive or negative ion and drag them with the mouse into the reaction center.
If you did not create the right solution, you will get hints like "add more sulfate" to build the correct formula.
To find out the name of the substance move the mouse cursor over the formula box.
To immediately show the formula, drag the ions directly to the formula box.
If your students think to be skilled in the knowledge of inorganic compounds, they may select the test mode which allows you to practice with formulae.
The program randomly selects ions from the level you have chosen.
The program
comes with tutorials in four different levels but teachers may create their own courses. You may add any ions you want to the database .
