Understanding Ionic Solids Dissolution Process

Learn about the phenomenon of how ionic solids dissolve, known as solvation. Water plays a crucial role in breaking apart the positively and negatively charged pieces of the solid, surrounded by water molecules. For a solid to dissolve, the water's attractive force must exceed that of the crystal's. Discover why water cannot dissolve nonpolar molecules due to their inability to interact with water molecules. Explore the interactions between water molecules and polar substances that enable dissolution.

  4. Solids will dissolve if the attractive force of the water molecules is stronger than the attractive force of the crystal. • If not the solids are insoluble. • Water doesn’t dissolve nonpolar molecules because it the water molecules can’t hold onto them. • The water molecule hold onto each other and separate from the polar molecules.
