Conductivity of electrolytes

At the end of this activity, students should be able to:
– know why some substances conduct an electric current in the molten state or in aqueous solutions
– know what electrolytes are
– explain how to distinguish between an electrolyte and a non-electrolyte
– give examples of electrical conductors
– determine which ions are present in a molten salt
– specify which ions are present in a solution of an electrolyte.
