This simplified microchemistry lab allows students to investigate some of the rules of solubility before you begin balancing double replacement reactions or making predictions about precipitates. This lab is appropriate for all levels of chemistry and also for physical science to demonstrate chemical reactions. Students then use what they've learned about these patterns of reactions to identify three unknowns.
Student investigate the precipitate reactions and solubility of the products for 7 reactants and 49 reactions. You will need a class set of 96 well spot plates and .1M solutions of 7 common reagents. In addition, you will also need 10 disposable thin stem micropipettes per group to create the kits. It takes approximately 45 minutes to complete the activity.
Once this lab is set up, it can be stored in a shoe box or similar and simply pulled out year after year. You’ll only need to top up your solutions!
Includes instructions for making the solutions, lab set up, kit set up and labels for pipettes.
