Argumentation and Documentation Classify each substance as metallic, ionic, molecular or covalent network based on your experimental results and further observations Part I. Testing Conductivity of Substances at Room Temperature Two substances were electrically conducting solids. The only classifications for substances that conduct electricity as solids are metallic or covalent network solids. Use the malleability property of metals to determine the classification of the two substances. Part II. Testing Conductivity of Solutions You tested only three substances for aqueous solution conductivity. Strong conductivity In solution is indicative of only one type of ionic compound, because soluble lonic compounds dissociate into ions. Part III. Testing Conductivity of Pure Liquids Low melting temperatures and liquids that do not conduct electricity are characteristic of molecular substances. Which substances would be classified as molecular substances? Justify each conclusion with at least two properties. Classification Justification 1 Justification 2 Substance Aluminum Ascorbic acid Graphite Paraffin Palmitic add Sodium chloride Sucrose Water Extension Activity is a gas at room temperature and does not conduct electricity. Yet when dissolved in water, the solution becomes an excellent conductor. Classify HCl as metallic, ionic, molecular of covalent network, and explain why HCl would conduct electricity in an aqueous solution
