Unformatted text preview: Ocean County College Department of Chemistry LAB 7: Identification of Metallic Ions Submitted by Colin M. Campbell Date Submitted: 18 MAR 2010 Date Performed: 17 MAR 2010 Lab Section: DL2 Course Instructor: Professor Maria Tamburro Ocean County College 1 General Chemistry I DL2 Chemistry Department Purpose: Is to investigate the chemical properties of pure chemical substances, and to investigate the physical properties of pure chemical substances. Chemical properties describe the tendencies of a substance to undergo chemical change. Physical properties commonly used to characterize pure substances are: color, melting point, odor, boiling point, hardness, density, and solubility. The observation of physical change does not involve chemical change in the substance. Each new product formed as a result of chemical change has its own set of characteristic chemical and physical properties. We will follow the procedures to properly identify chemical and physical changes in 7 substances. Procedure: I began the experiment by acquiring all necessary materials that I needed to provide (toothepicks and matches), and then sifting through my ChemKit to find...
