Assessing Students' Conceptual Understanding of Solubility Equilibrium Andrés Raviolo
A problem about solubility equilibrium is presented as a resource for the evaluation of students; it involves macroscopic, microscopic, and symbolic levels of representation, and allows one to assess whether students have acquired an adequate conceptual understanding of the phenomenon.

The Ksp-Solubility Conundrum Roy W. Clark and Judith M. Bonicamp
The authors sought to find those cases of partly soluble substances for which simple calculations such as Ksp=S2, and Ksp=4S3 can realistically be used for computing solubility from Ksp and the reverse calculation. Empirical solubility data are compared with solubilities calculated from reliable Ksp values that have been adjusted for activity coefficients. A table of 18 substances is suggested for textbook use.

Miscellaneous Alyea, Hubert N.
These twelve overhead projection demonstrations include rates of reactions, clock reactions, the effect of temperature and the presence of a catalyst on the decomposition of hydrogen peroxide, the relationship between viscosity and temperature, equilibria, solubility product, and the common ion effect.

Are solubilities and solubility products related? Meites, Louis; Prode, J. S. F.; Thomas, Henry C.
The relation between solubilities and solubility products is far less intimate than is stated or implied by introductory texts and the ideas and calculations involved are too complex for presentation on the elementary level.
