Reaction, Microscale: Potassium Dichromate with Silver Nitrate A crystal of potassium dichromate is carefully combined with a solution of silver nitrate under a microscope. The reaction takes some time, so it is shown in a series of seven sequential videos. To see the entire reaction you need to play all seven.
Predominance Diagrams, a Useful Tool for the Correlation of the Precipitation–Solubility Equilibrium with Other Ionic EquilibriaConstantino Fernández Pereira, Manuel Alcalde, Rosario Villegas, and José Vale Similarities among various types of ionic equilibria have led to a unified treatment of equilibria problems using diagrams that employ the logarithm of the exchanged particle's concentration as the variable. This paper focuses on precipitationsolubility equilibria and describes the usefulness of such diagrams for solving solubility problems.

Students' Understanding of Solution Chemistry ConceptsTacettin Pinarbasi and Nurtaç Canpolat This study examines undergraduates' understanding of some concepts in solution chemistry such as unsaturated, saturated, and supersaturated solutions; physical properties of solutions; and gas solubility. We suggest that the results can be utilized in research that develops teaching strategies to overcome students' misunderstanding. Pinarbasi, Tacettin; Canpolat, Nurtaç . J. Chem. Educ.2003, 80, 1328.

The Solubility Product of PbCl2 from Electrochemical MeasurementsJimmy S. Hwang and Ghassan A. Oweimreen Students obtain the solubility product, Ksp, of PbCl2 at various temperatures from practically simultaneous emf measurements on two electrochemical cells. One half-cell is common to both cells. Hwang, Jimmy S.; Oweimreen, Ghassan A. J. Chem. Educ.2003, 80, 1051.
