To perform the experiment, we had to carry out this experiment in well-ventilated area because the volatile unknown liquid could have been flammable, toxic, or irritant. In addition to that, we also had to wear department safety goggles, avoided skin/clothing contact, and most importantly, tried not to inhale any of the vapor. Now to actually perform the experiment, we placed a boiling stone into a 25 mL Erlenmeyer flask. Using a small piece of aluminum foil and a rubber band we sealed the mouth of the flask. We pinched a small hole in the center of the aluminum foil, and we measured the mass of the dry flask, boiling stone, and foil cap to the nearest 0.001 g. We obtained about 25mL of an unknown volatile liquid using a 10 mL graduated cylinder. We meticulously took …show more content…

We fasten a clamp to the neck of the flask, covering the foil cap with the clamp. We prepared a hot-water bath by placing approximately 150-200 mL of tap water into a 400 mL beaker. We attached a support ring to a ring stand. We placed the beaker through the ring. Adjusted the ring to stabilize the beaker while it was sitting on a hot plate. We suspended the flask at a slight angle, up to its neck in the water bath, making certain that the water never touched the foil cap. To suspend a thermometer in the water we rolled a piece of napkin paper, and used a clamp to supported to the apparatus, making certain that the thermometer bulb didn’t touch the bottom of the beaker. We turned on the heating plate, and boiled the water in the water bath. We waited for the whole unknown liquid to vaporize, and recorded the water-bath temperature. As soon as the liquid completely vaporized, we removed the clamp-flask assembly from the water bath. We turned off the hot plate. By holding the flask and its contents under cold tap water we cooled down. After the flask cooled down, and the flask vapor condensed back into a liquid, we removed the clamp from the
