BOND TYPES: THE CLASSIFICATION OF SUBSTANCES Purpose You will be given eight unknowns to determine what type of solids they are: ionic, covalent, macromolecular or metallic on the basis of their physical properties. Procedure You will estimate the (a) melting points;(b) solubilities in 3 different solvents, (c) conductivity as a solid and an aqueous solution. On the basis of your observations, you are to classify each one as a member of one of the 4 main types of solids (ionic, molecular, macromolecular, or metallic) and cite supporting evidence for your choice. Planning Before starting your lab discuss with your partner and instructor your procedure and organize your data table. Melting Point Place a small amount of the solid to be tested in a test tube and heat the test tube in a beaker containing boiling water. If the solid melts in the boiling water bath, its melting point is at or below 100°C, the boiling point of water. If the substance does not melt in the boiling water bath, place a sample of it in a crucible supported on a triangle and heat it gently heat with the Tirrill burner. If the solid melts, its melting point
