Reactions : IDSampleRxnVideo (7 Variations) You have an unknown aqueous sample. You add aqueous copper(II) sulfate to the sample. View the video below and determine which of the compounds listed below could be your sample.
Dynamic Reaction Figures: An Integrative Vehicle for Understanding Chemical ReactionsEmeric Schultz Describes the dynamic reaction figure, a flexible learning tool that can be used to balance chemical equations, predict the results of potential reactions, present the underlying mechanism of reactions, and solve quantitative problems in a number of areas. Schultz, Emeric. J. Chem. Educ.2008, 85, 386.

Investigating Students' Ability To Transfer Ideas Learned from Molecular Animations of the Dissolution ProcessResa M. Kelly and Loretta L. Jones This study examines what features of the particulate nature of matter learned from viewing two animations of sodium chloride dissolution students would transfer to their descriptions of the participation of aqueous sodium chloride in a chemical reaction. Kelly, Resa M.; Jones, Loretta L. J. Chem. Educ.2008, 85, 303.

Solubility Rules: Three Suggestions for Improved UnderstandingBob 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. Blake, Bob. J. Chem. Educ.2003, 80, 1348.

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.
