A Multi-Colored Equilibrium Experiment

Solutions of copper (II) dissolved in acetone are easy to prepare, and can display orange, yellow, green, and blue color depending upon conditions. Such solutions allow for a variety of demonstrations and experiments that illustrate principles of chemical equilibrium. 

The Chemical Laser Show

Chemistry and lasers can be used to create a demonstration that includes several colors and flashing lights. This demonstration connects to topics in quantum chemistry and phase changes.

Chemical Tests on Coins

Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"

Element of the Month - Iodine

In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Iodine is the fifth in this series of elements to be discussed as part of the Element of the Month program. #IYPT
