- Properties of Ionic Compounds
- High melting and boiling points
- Ionic compounds are solid at room temp
- Therefore a large amount of energy is needed to break the strong electrostatic forces that hold the oppositely charged ions together in the solid ionic lattic.
- Ionic compounds are solid at room temp
- Solubility
- The ionic lattice dissolves in water
- The water molecules break down the lattice surrounding each ion to form a solution
- E.g. When NaCl is dissolved in water, the giant ionic lattice breaks down
- Water molecules attract Na+ and Cl- ions, the ionic lattice breaks down as it dissolves. water molecules surround the ions.
- Na+ attracts (negative -) charges on the O atoms of the water molecules and Cl- attracts (delta+) charges on the H atoms of the water molecules
- Water molecules attract Na+ and Cl- ions, the ionic lattice breaks down as it dissolves. water molecules surround the ions.
