Freezing and Melting of Paradichlorobenzene
Purpose:
Melting, freezing, and boiling points are properties that can easily be determined and help in identifying a substance. These properties can be found in chemical literature ad reference tables, and can be used to distinguish a pure substance from many other pure substances. In this lab you will use the pure substance Paradichlorobenzene and determine its melting an freezing points by warming and cooling a sample of the substance, then plotting heating and cooling curves and analyzing them. Data that you collect will represent the heating and cooling behavior common to all pure substances.
List of Materials:
-Large Test Tube (18*15 mm) -Safety goggles -Paradichlorobenzene
-Hot Plate -Lab Apron -Acetone
-Test Tube Holder -Ring Stand
-2 Thermometers -A Ring Clamp
