"LIKE DISSOLVES LIKE" is a saying that describes the solubility of substances. Use this magnetic molecular model set to demonstrate the dissolution of salt in water. Sodium and chloride ions are magnetically attracted to the water molecules and separated from the crystal. Build ethanol and water to show that similar structures are infinitely soluble (fully miscible). In contrast, build hexane and water to illustrate the unlike structures of insoluble substances. .
PARTS TO THE SOLUTIONS SET
2 MAGNETIC WATER MOLECULES = 2 oxygen + 4 hydrogen + 4 bonds (25mm)
