Titration of a Solid Acid Monitored By X-Ray Diffraction  Keenan E. Dungey and Paul Epstein
Presents a solid-state laboratory in which students react fixed amounts of zirconium phosphate with increasing equivalents of NaOH(aq). From X-ray diffraction patterns, students calculate the interplanar spacings before and after the reaction. The spacings increase until the molar equivalence point is reached, indicating incorporation of the sodium ion into the crystal.

Sherlock Holmes and the Case of the Raven and the Ambassador's Wife: An Inquiry-Based Murder Mystery  Nathaniel Grove and Stacey Lowery Bretz
In the accompanying investigation, students help Sherlock Holmes solve the poisoning death of Holly Bernard-Schneider, the wife of the German ambassador to England. Hints are placed throughout the story to help students in their choice of experiments. These experiments include flame tests, qualitative analysis, molar mass determination using freezing point depression, and identification of crystal shapes. Though intended for use as a culminating activity, the unit can be easily modified to be used as separate modules throughout the course of the year.
