2018-5-21 · The terms melting point or freezing point are often interchanged depending on whether a substance is being heated or cooled. For liquids it is known as the freezing point and for solids it is called the melting point. The melting point of a solid and the freezing point of the liquid are normally the same.

Why Do Ionic Compounds Have High Melting and …

Ionic compounds have high melting and boiling points because the ionic bonds that hold the compounds together are very strong and require a great deal of energy to break apart. A higher temperature indies that more energy is being used. This extra energy is needed to break the electrostatic attraction that is present in an ionic bond.
