Lab Report Boiling Point and Melting Point
repCHEMISTRY I - LABORATORY EXERCISE MANUAL
LABORATORY EXERCISE 10: Melting Point and Boiling Point Determination
This is a traditional lab. You'll simply follow the step-by-step procedure, keeping records of your measurements and observations. Each student will write their own lab report, which should include the following:
Name:
Names of lab partners:
Date of Experiment:
Date Report Submitted
TITLE:
Purpose: A brief statement about what the experiment is designed to determine or demonstrate about chemistry
Procedure: Brief summary
Data Tables:
Observations:
Conclusions: What did you learn from the experiment? Should be based on observations made during the experiment.
Evaluation of laboratory exercise type:
On a separate page, each student should write a brief comment regarding
1) which lab method you prefer (inquiry-method, i.e. problem-solving oriented, or traditional lab. like this one.
2) group size (individual labs or small-group labs)
3) report writing - individual or small group
4) Any negative aspects about chem lab & how we can improve them
5) any other comments
We expect an evaluation from everyone. If you prefer not to put your name on this evaluation, that's Ok.
Lab Instructions:
Objectives:
1. To determine the boiling point of a liquid, and
2. To determine the melting point of a solid.
Materials Used:
Matches
Isopropyl (Rubbing) Alcohol
1-2 small rubber bands
Thermometer
Powdered Acetamide<br< stand beaker
2 closed-end capillary tubes (melting point tubes)
10-12 mm diameter test tube
Heat source
Discussion and Review:
In this experiment we will examine additional physical properties of liquids and solids. Two of the more important physical properties of pure substances are the boiling point and the melting point.
The boiling point of a liquid is the temperature at which that liquid is converted to a gaseous state. Boiling point is formally defined as the
