Synthesis, Dehydration, and Rehydration of of Calcium Sulfate (Gypsum, Plaster of Paris)

by Greg Sirokman


Engaging students who are not chemistry majors is a significant challenge.  Plaster of Paris is a substance well-known to undergraduate students from early life arts-and-crafts endeavors.  Within, a lab is described that connects the synthesis and use of plaster of Paris with a number of chemical principles including stoichiometry, acid-base titration, hydration, and reaction yield.
