Chemistry Zone Lesson: Electrolytes

An electrolyte is a substance that when dissolved in water forms a solution that can carry an electric current (flow of charge).  In the simulation below, each time you click the play button the continuity tester will be placed in a solution.  The brighter the light bulb glows, the more current is being conducted by the solution.  The stronger the current, the stronger the electrolyte.

The ability of a solution to conduct electricity is the result of ions being present in the solution.  Electrolytes include all ionic compounds as well as many polar covalent compounds such as acids that react with water to form ions. 

The more ions present, the more brightly the light bulb will glow.
