  Activity: Advanced Modeling of the Dissolving Phenomenon Mark as Favorite (29 Favorites)

  In this activity students build a model of sodium chloride based on their own knowledge of ionic compounds. Then they construct a model of the interactions between water and their salt model to develop an understanding of what caused the salt to dissolve. After refining their models based upon class discussions and critiques, students then construct a model of the interaction between salt and a different solvent, alcohol. Using their models, students make predictions as to which solvent (water or alcohol) would be better at dissolving the salt. Finally students design an experiment to test their prediction. As an extension, students are asked to use their solubility models to explain why calcium carbonate will not dissolve in water, even though it is also an ionic compound.

  Animation: Solubility Animation Mark as Favorite (76 Favorites)

  This animation explores how ionic and molecular compounds dissolve (or don’t) in water. Students will see that if an ionic compound such as salt dissolves, the ions dissociate, whereas the molecules in a molecular compound such as sugar remain intact but are separated from one another by water molecules. They will also see that some ionic compounds such as chalk do not dissolve, and the cations and anions remain stuck together. **This video has no audio**
