Abstract: Cosmetic chemistry is a prevalent part of everyday life, but there are very few undergraduate laboratories that explore this topic.…
Students tackle the deceptively simple task of determining the pressure of carbon dioxide gas inside a sealed soft drink can.
By Hans de Grys, Journal of Chemical Education 2007, 84, 7, 1117
Abstract Soft drinks provide a unique way to explore chemical principles. A challenging exercise for students is to determine the pressure of the carbon dioxide gas inside…
Students investigate 8 household white powders and classify them based on their physical and chemical properties. Using their findings, students then identify an unknown powder obtained from a crime scene to determine the suspect's guilt or innocence. Students gain experience in the identification of chemical and physical changes, careful organization of data, and writing chemical reactions.…

Many covalent and ionic compounds are solids at room temperature. Solids may exist as crystalline solids—that is, ordered arrays of atoms, ions, or molecules—or as amorphous solids, which have random or disordered arrangements of particles. There are several types of crystalline solids. In this lab, you’ll be creating…

Students use household materials and a conductivity probe to explore factors that affect the conductivity of electrolytic solutions. Students gain experience in molarity and dilution calculations, solution preparation, nomenclature, statistical analysis, and graphical presentation of data. This hands-on activity is flexible and can be modified to accommodate both high school and undergraduate courses. Students can safely…

If you’ve ever made ice cream at home, you know the recipe calls for adding salt to ice to cool down the ingredients enough for the ice cream to actually freeze. What’s up with that? Or why do road crews add salt to roads in…
Students synthesize the copper pigment malachite, then use the pigment to prepare egg tempera paint. Students explore "stoichiometry (excess reactants and yields), solubility, precipitation, and properties of emulsions" in this Journal of Chemical Education article by Sally D. Solomon, Susan A. Rutkowsky, Megan L. Mahon, and Erica M. Halpern.
The first half of this experiment uses…
Hands-on learning in a remote laboratory environment.
This Journal of Chemical Education Article by Deon T. Miles and William G. Wells of the Department of Chemistry, Sewanee: The University of the South describes a homemade kit with at home, hands on laboratory experiments in spectroscopy and chromatography. The paper and supporting information describe both hands on…
