Abstract The following report explains the process of identifying and synthesizing an unknown ionic compound. Initially, all experimenters were provided with four unknown ionic compounds by the laboratory instructor. Throughout the experiment, chemical properties of the unknown compounds were determined by various laboratory tests. Once all compounds were identified, one was chosen to undergo the remainder of the laboratory procedure. Using the identified properties, the chosen compound was determined to be calcium carbonate. When added to a pure water solvent, the compound was found to be poorly soluble. Further testing suggested the compound to be slightly basic. A titration procedure was used to accurately assess the molecular weight of the compound. Laboratory data resulting from each applied procedure supported the hypothesis that the compound was calcium carbonate. Introduction The goal of this laboratory experiment was to identify the provided compound by exploring its chemical properties. Four containers labeled with an individual letter had been distributed to each laboratory team with the intention that the experimenters identify all four compounds. Successful execution of this experiment was important in developing the proper laboratory skills necessary for future experimenting. One compound was chosen to endure the remainder of the laboratory procedure once all four had been identified. Identification of physical and chemical properties was done through a series of tests including a solubility test, conductivity test, litmus paper test, flame test, anion test, and cation test. Simple observations were used to investigate some of its physical properties while also noting what occurred during each chemical reaction. Further investigation of chemical properties included both qualitative and quantitative analyses of the ions in the compound. A titration procedure was used to quantify the molecular weight of the compound. Finally, the laboratory procedure called for three possible syntheses of the compound in order to explore which reaction would be the most desirable given the situation. The proper synthesis, analysis, and identification of the unknown were the major goals of this experiment.
