Qualitative Analysis II
 
This model will help you understand how to solve the simpler qualitative analysis problems, teaching you to identify the substances that are located in the test tubes 1, 2, and 3. The list of experimental substances is located in the model's main window. In the process of solving the problem, you will pour one substance from the upper row and one substance from the lower row into the flask, and see whether the reaction gives precipitate. To do that, drag the appropriate test tube towards the flask, and drop it when it supersedes the flask. Before you start any further testing, make sure to empty the flask by dragging it to the waste tank.

There are two possible feedback signals that you can receive from the model. A green checkmark indicates that the procedure is permissible while a red cross indicates that the procedure is prohibited.

Once you have determined which indicator is contained in the test tube, you can choose its name from a list that is located at the bottom of the model. After all three labels have been applied to the test tubes, press "Check" button in order to verify your answer. If your answer is wrong, press "Clean" button, and try again.
