ESSENTIAL PARTS OF A LAB REPORT

 

ABSTRACT: The abstract is a mini-paper and includes the objectives of the work, method(s) employed, summary of results and conclusions - all of which appear in the full report.

 

INTRODUCTION: The introduction should include the nature and scope of the problem, review of pertinent literature, and method of investigation.  It is not necessary to make an exhaustive literature search or to include entire sections of a physical chemistry text.  Rather, focus on necessary theory as it applies to your experiment.

 

MATERIALS AND METHOD: Describe all chemicals, their name, formula and purity; instruments used as well as their manufacturer and model number; detailed procedure of how you actually performed the experiment.  Give all data in neat tables, labeled with appropriate units.  If you analyzed an unknown, give its identifying number.  If you analyzed a known sample, identify it, describe it and give its source.

 

CALCULATIONS: Show all calculations.  Sometimes you may have to describe in words what you are calculating or the purpose of the calculation.  Clearly indicate the results of all calculations and results of the experiment.  Use tabular form to present your results if they are extensive.

 

RESULTS and DISCUSSION: In this section give your conclusions and evidence for each conclusion.  Relate your work to known previous work.  Point out exceptions, unsettled points, and any errors you are aware of.

 

REFERENCES: List all significant references in complete form for citations.  Examples are:

            JOURNAL ARTICLES:  Huffman, J.C.; Lewis, L.N.; Caulton, K.G.  Inorg. Chem.  1980, 19, 2755
