Properties of Ionic Compounds Form crystalline solids

Properties of Ionic Compounds Very, very high melting points Very, very high boiling points Bonds are very strong so it’s hard to move the molecules apart

Properties of Ionic Compounds Very strong Takes a lot of force to break them Very Brittle Given enough force it shatters

Ions in Solution Conduct electricity Electrons can move from ion to ion freely, so an electrical current can move through the solution.

Ions in Solution Increase boiling point Ions attract the solvent molecules Takes more energy to pull the solvent molecules far enough apart to become a gas.

Ions in Solution Decrease freezing point The ions are stuck between solvent molecules. The energy level must be lower for the solution to freeze
