Question

why is Sodium Chloride a high melting point

Answer 1

Hey there !

Sodium chloride has a high meltingand boiling point. There are strong electrostatic attractions between the positive and negative ions, and it takes a lot of heat energy to overcome them. Ionic substances all have high meltingand boiling points.

Hope it helps you !

Answer 2

Sodium chloride is an ionic compound with strong electrostatic attractions between the positive and negative ions. It takes a lot of heat energy to overcome these attractions and therefore sodium chloride has a very high melting and boiling point.
