Identification, Properties, and Synthesis of an Unknown Ionic Compound Chemistry 101 Laboratory, Section 043 Instructor: Matthew Zimmerman November 12, 2008 Abstract An unknown compound needed to be identified for environmental reasons so it could be properly handled and disposed. In order to identify this compound, tests were performed, including a flame test which revealed the cation and precipitation tests which led to the discovery of the anion. These tests led to the hypothesis of the unknown compound. Other tests were performed on the unknown compound to find its physical and chemical properties. These tests were also performed on a sample of the suspected compound and the results were compared. Once the compound was clearly identified, the compound would be synthesized through an acid-base reaction, producing the compound and water. The compound was removed from the water, by vacuum filtration, and the sample was dried and a percent yield was calculated to further prove that the unknown compound is what it was predicted to be. My signature indicates that this document represents my own work. Outside of shared data, the information, thoughts and ideas are my own except as indicated in the references. In addition I have not given aid to another student on this assignment. Introduction

An unknown compound needed to be identified for environmental reasons so it could be properly handled and disposed. In order to identify this compound, various tests were performed, including a flame test which revealed the cation, and precipitation tests which led to the discovery of the anion. These tests led to the hypothesis that the unknown compound was sodium sulfate. Other tests were performed on the unknown compound to find its physical and chemical properties. These tests were also performed on a sample of the suspected compound and the results were compared. Once the compound was clearly identified, the compound would be synthesized through an acid-base reaction, producing the compound and water. The compound was removed from the water, by vacuum filtration. The sample was dried and a percent yield was calculated to further prove that the unknown compound is what it was predicted to be. Results Tests for initial identification: Conductivity Flame test Solubility test Precipitation reactions Test Result Conductivity Not conductive Flame Test (for cation) Orange Sodium (Na + ) Table 1 shows that the unknown compound was not conductive and that it contained sodium.
