Document Summary
Introduction: to learn how to investigate the physical property of boiling point. To carry out experiments using a micro technique and calibration curve. Chemical responsibility: the unknown chemicals have hazards associated with them: methanol, isopropyl alcohol, and ethanol are flammable liquids and are toxic by ingestion. Wear goggles to protect your eyes from the chemicals, and avoid touching broken glass. Be careful while putting the rubber stopper on the thermometer, for it can break. Throw all broken glass in the broken glass box, and discard the unknown liquid from the small test tube into the bottle labeled. Report sheet and sample calculations: see attached sheet and graph. Results: the boiling point was determined through the assembly of a thermometer attached to a small test tube with rubber bands. Inside the test tube was a capillary tube submerged with an unknown liquid. This liquid/thermometer apparatus was placed in a beaker filled with water.
