dissolved form of the substance and if the light flashed on‚ then the substance conducted electricity when dissolved. I think substance 1 is a covalent compound. This is because it had a low melting point during the melting point test. Substance 2 might be a metallic compound because it had a high melting point but also low solubility in water. I think substance 3 is an ionic compound because it had a high melting point and solubility in water. Substance 4 may be a metallic compound because it
