Properties of ionic compounds:
• Ionic bonds are very strong.
• High melting and boiling points due to the strength of their bond.
• Most are crystalline solids at room temperature.
• Does not conduct electricity in solid state, but does in the liquid and aqueous states. In the
solid state, the ions are locked into fixed positions by strong attractive forces. In the liquid
and aqueous states the particles can move freely.
• Hard but brittle. Any dislocation leads to the layers
moving and similar ions being adjacent. The
repulsion splits the crystal.
• Soluble in water.
