If a solute produces ions when dissolved, it is called an electrolyte because the resulting ions in solution will allow the solution to conduct electricity. A solute that completely dissociates into ions is a stronger electrolyte than one that only partially dissociates into ions. If a solute remains as a molecule when dissolved, it is called a nonelectrolyte.In this tutorial, you will practice identifying substances as strong electrolytes, weak electrolytes, or nonelectrolytes.
