Question 5

Why do ionic compounds have high melting and boiling points?

Answer 5

Ionic bonds are very strong and a lot of energy is needed to break them.

Question 6

Explain why ionic substances don’t conduct electricity when solid but do when melted or dissolved in water.

Answer 6

In a solid state the ions wont conduct because they can not move, however in a liquid state they will conduct because the ions are fee to move and act as charge carriers.
