Strong, Weak, or Non-Electrolyte?For the purposes of this course, use these criteria to determine if a substance is a strong,weak, or non-electrolyte when dissolved in water (aqueous solution):1.All ionic compounds are strong electrolytes, because they mostly break up into ions asthey dissolve in water. Even insoluble ionic compounds (e.g., AgCl, PbSO4, CaCO3) arestrong electrolytes, because the small amounts that do dissolve in water do so principallyas ions; i.e., there is virtually no undissociated form of the compound in solution.2.Molecular compounds may be non-electrolytes, weak electrolytes, or strong electrolytes,depending on whether they dissolve without ion formation, a little ion formation, ormostly ion formation, respectively.
