A strong electrolyte is a substance that completely dissociates into ions when dissolved in water. A weak electrolyte is a substance that does not completely ionize in water and only weakly conducts electricity in solution. A non-electrolyte is a compound that does not dissociate into ions when dissolved in water.
Work Step by Step
Non-electrolyte solutions do not conduct electricity. Weak electrolyte solutions do somewhat, and electrolyte solutions using stronger electrolytes conduct electricity well.
