A common prank on college campuses is to switch the salt and sugar on dining hall tables. which is usually easy because the substances look so much alike. Yet, despite the similarity in their appearance, these two substances differ greatly in their properties because one is a molecular solid and the other is an ionic solid. How do the properties differ and why?
