Why do ionic compound have high melting point???? |
|
Answer» Ionic compounds have high melting points because there is a strong electrostatic force of attraction between the oppositely charged ions and hence a large amount of energy is required to break the strong bonding force between ions.\xa0 \tIonic compounds have an equal number of positive and negative ions arranged in the three-dimensional lattice due to which they have high melting points.\xa0\tThe strong force of attraction between oppositely charged ions means that ionic compounds have high melting and boiling points.\xa0\tWhen dissolved in water ionic compounds form a solution in which ions can move. This means that these solutions can conduct electricity.\tSimilarly, if ionic compounds are heated up so that they melt the ions can move and molten ionic compounds can also conduct electricity. |
