Melting Point Determination Lab Report

The labs are intended to make you use the scientific method, to understand, and to reinforce

concepts learned in class. If you need help, please ask.

The lab reports must be typed or clearly written and the pages stapled together. Reports must be

neat or they will not be accepted.

Use passive language when writing a report; avoid using personal pronouns (I, We).

Part II. Materials and Methods

detailed list of chemicals and equipment used (ex. 1.0 M sulfuric acid, Buchner funnel)

chemical structures of organic reagents used

procedure you followed with enough detail that someone who only had your report could

do the experiment

Part III. Results

chemical reaction equations if conducting a synthesis

observations

any measurements, data sheets, calculations, handouts, drawings, photos, etc.

Part IV. Discussion

-define new terms

-discuss the theory behind the experiment; incorporate relevant terms and definitions

-analyze or interpret your results

-discuss your experimental results/calculations versus theoretical

-discuss any mistakes or possible sources of error and their impact

Part V. Conclusion
