The solution of an electrolyte has the ability to conduct an electric current. A strong electrolyte dissociates or ionizes almost completely into ions, whereas a weak electrolyte undergoes only limited ionization or dissociation. The solution of a nonelectrolyte does not conduct a current because few, if any, ions are present in the solution. The electrical conductivity of a solution can easily be measured with a meter or a light bulb. The total ion concentration of any solution is determined by both the type and the concentration of solute. The electrical conductivities of the following 0.100…

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.
