Methods of Analysis Test #1: Polarity, or Effect of a charged rod on a stream of liquid: This test was used to determine the relative polarity of the unknown liquid. The liquid was allowed to run out of a buret and a charged rod was brought up next to the stream. The observations were reported as to whether or not the stream of liquid responded to the charged rod and to what degree. Try this at home with water and a plastic spoon. Rub the plastic spoon against a sweater and move it close to a small stream of water running out of your faucet! Test #2: Volatility, or Rate of Evaporation: A thermometer probe was wrapped with a strip of filter paper. This assembly was soaked in one of the liquids for one minute. The probe was removed, and the temperature change was monitored as the liquid evaporated. The results are given in Graph 1 below. (See Graph)   Graph 1: The curves generated of the change in temperature over time for the substances acetone, hydrogen monoxide, ethylene glycol,…
