Properties of Ionic compounds

Question 1

High Melting and Boiling Point

Answer 1

The strong electrostatic force of attraction between the ions require a lot of energy to break.

Question 2

Mostly soluble in Water

Answer 2

Water molecules are able to break the electrostatic force of attraction between the ions because water molecules and ions have a stronger force of attraction than the attraction between the ions. This is because water is polar.

Question 3

Ionic Solids don’t conduct electricity

Answer 3

Ions in a solid ionic compound are not free to move

Question 4

Ionic compounds conduct electricity when dissolved in water or molten

Answer 4

Ions are free to move and carry an electrical charge

Question 5

Brittle

Answer 5

When a force is applied, the ions in the lattice shift so that like ions repel and the lattice breaks

Question 6

Hard

Answer 6

Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions
