Solid salt doen’t conduct electricty. Why does dissolving it in water help it to conduct electricity?

  1. It is because of the nature of ions. Electric conduction is based on free valence electrons. When solid, the Na’s free electron is bonded w/ Cl, meaning it is not free to interact. Because water is a polar substance, it is strong enough to break them apart into ion forms (Na+ and Cl-), freeing the electrons and conducting electricity.

  2. Dissolving salt in water can conduct electricity, since the salt becomes its aqueous state when dissolved, which means the salt is seperated into its ions, ions are substance that contains mobile electrons that conduct electricity!!
