How does a conductivity apparatus test whether a solution has ionic or covalent substances in it? It fails to light up except in homogeneous solutions. It lights up when the leads touch each other. Ions complete the flow of electrons to form a circuit. The covalent substances bond to the leads to prevent the lightbulb from lighting.
