Question

How are the dissolved particles of a molecular solid, such as sugar, different from the dissolved particles of an ionic solid, such as table salt?

Answer 1

The dissolved particles of a molecular solid exist as discrete molecules in the solution. The molecules are relatively weakly bound to the water molecules and uncharged.

The dissolved particles of an ionic solid exist as the separate positive and negative ions (so for sugar we have only sugar molecules; for salt we have Na+ ions and Cl- ions separately). The ions are bound more strongly to the (polar) water molecules than are the molecules of a molecular solid. They are always in the same relationship to the nearby water molecules - for instance, the Na+ ion will attach itself to the negatively charged oxygen area, and the Cl- ion to the hydrogen ends.
