Experiment Four Discussion The first step in deducing the identity of the unknown was to determine if my unknown had a dipole moment, or was to some degree polar. In order to test for polarity, I set a steady stream of my unknown close a charged rod and observed for a bend in the stream. If there was a bend in the stream I was able to determine the molecule was polar. In addition to this charged rod test, I tested the unknown’s solubility in water. If the unknown was miscible with water, then I determined that the unknown was polar. The charged rod test was a more sensitive test for polarity, because some molecules that have a dipole moment are not soluble in water. If the unknown was immiscible in water, then I tested its density in relation to water. To do this, I poured the top layer of the solution (the less dense layer) on a small sample of sodium chloride. If the sodium chloride dissolved when the top layer was introduced, then the top layer could be identified as water. In this
