  Animation: Solubility Animation Mark as Favorite (78 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**
