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.

Annotating reaction equations  Tykodi, R. J.
Annotating aqueous solution reactions fosters recognition of the fundamental reaction categories; ready recognition of a reaction type is the first step toward understanding the "whys and wherefores" inherent in the reaction.

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.
