Determining the Solubility Product of Fe(OH)3: An Equilibrium Study with Environmental Significance  Michelle Meighan, Joseph MacNeil, and Renee Falconer
This study explores the environmental impact of acidic mine drainage by investigating the relationship between pH and the aqueous solubility of heavy metals. Students precipitate Fe(OH)3 from acidic FeCl3 and NaOH and use the concentrations of ferric and hydroxide ionsdetermined through pH and flame spectroscopyto calculate the Ksp of Fe(OH)3.

Solubility Rules: Three Suggestions for Improved Understanding  Bob Blake
Many general chemistry textbooks have errors or omissions in their rules for predicting solubility that the author highlights and attempts to correct. In addition, it is proposed that the following changes be made to the discussion of solubility so that students and teachers can have a greater understanding of solubility.

Modification of Small-Scale One-Pot Reactions to an Inquiry-Based Laboratory Exercise  C. Jayne Wilcox
Students are given an initial handout and asked to complete a short, attention-getting exercise. They must continue to work on logical, short exercises given to them one at a time, in handout format. The inquiry-based approach is intended to increase students' comprehension of what they're doing in the laboratory and why.

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.
