Precipitation Reactions Two versions of the Orange Tornado, two reactions under a microscope, and updated stills of other precipitation reactions provide dramatic visual displays of solid formation.
Determining the Solubility Product of Fe(OH)3: An Equilibrium Study with Environmental SignificanceMichelle 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 ionsdetermined through pH and flame spectroscopyto calculate the Ksp of Fe(OH)3. Meighan, Michelle; MacNeil, Joseph; Falconer, Renee. J. Chem. Educ.2008, 85, 254.

A New Java Animation in Peer-Reviewed JCE WebWareWilliam F. Coleman and Edward W. Fedosky Just added to JCE WebWare, Computer Simulations of Salt Solubility uses a Java applet and Web browser to present an animated illustration of differences in the solubility of salts due to differences in the entropy of solvation. Coleman, William F.; Fedosky, Edward W. J. Chem. Educ.2006, 83, 173.

Computer Simulations of Salt SolubilityVictor M. S. Gil, João C. M. Paiva Computer Simulations of Salt Solubility provides an animated, visual interpretation of the different solubilities of related salts based on simple entropy changes associated with dissolution: configurational disorder and thermal disorder. This animation can also help improve students conceptual understanding of chemical equilibrium before any quantitative interpretation of equilibrium constants is attempted.
