1.34 understand that ionic compounds have high melting and boiling points because of strong electrostatic forces between oppositely charged ions
To melt or boil anything, heat is used to break bonds. The stronger the bonds, the more heat needed. Ionic compounds have strong bonds, so they don't melt or boil unless there is a considerable amount of heat, this means the have high melting and boiling points.
