Sophie Scheidlinger March 12, 2008 Whittling Down the Possibilities: Identifying An Unknown Using Dipole Moment, Solubility, Density, and Boiling Point Purpose: To use observation of dipole moment, solubility in water, density relative to water, and boiling point measurement to identify an unknown compound. Discussion: In this experiment, either three or four tests were performed in order to identify four unknown compounds from a list of 16 compounds. Each of these compounds had a specific set of measurements that would be used to identify each compound. Dipole moment, solubility in water, density relative to water, and boiling point were all used to identify the unknown chemical. The four tests were conducted and recorded in order to narrow down the possibilities. From information given and past knowledge about compounds, each compound has a specific set of properties. Once these properties are determined one can identify the unknown compound. For instance if one of the unknowns had a dipole moment, one would know that this unknown will not be a molecule that has been identified as a molecule without a dipole moment. Then the next
