Preparation and Analysis of Multiple Hydrates of Simple Salts Richard W. Schaeffer, Benny Chan, Shireen R. Marshall, Brian Blasiole, Neetha Khan, Kendra L. Yoder, Melissa E. Trainer, and Claude H. Yoder
A laboratory project in which students prepare a series of hydrates of simple salts and then determine the extent of hydration of the product(s); provides a good introduction to the concepts of solubility, saturation, recrystallization, relative compound stability, and simple gravimetric analysis.

The Solubility of Ionic Solids and Molecular Liquids C. Baer and Sheila M. Adamus
The solubilities of three ionic salts (NaCl, PbCl2, and KAl(SO4)2.12H2O) in water are measured at four temperatures. The concept of recrystallization is introduced as students cool a high-temperature solution and observe crystal formation. Spreadsheet calculations are performed with the group data, which are then graphed, and students observe the wide variance in solubility behavior for the three salts.

Sealed tube experiments Campbell, J. A.
Lists and briefly describes a large set of "sealed tube experiments," each of which requires less than five minutes to set-up and clean-up, requires less than five minutes to run, provides dramatic results observable by a large class, and illustrates important chemical concepts.
