LABORATORY REPORTS instruction
Objective- Carefully study and record what you are trying to do. One or two sentences are
usually sufficient to indicate the goals of the experiment. Refer to the manual.
Theory- This section should provide the chemical basis of the experiment with balanced
equations and any mathematical equations needed to do the calculations. All terms used in
equations should be defined.
Procedures – Do not make a list of steps. In paragraph form, give a brief synopsis of the process,
and detail any deviations from the lab book directions.
Data – Use tables and graphs. Label them carefully and clearly, making sure that the units are
included. Enough data should be given to be able to calculate answers, but not all raw data are
necessary.
Calculations– You must take a set of your data and show a sample calculation in detail
Results with statistical analysis- Report the results along with your unknown number in bold
or highlighted in some way. Results have to be in the recommended units (concentration, wt.%,
mg etc.). Statistical analysis of data in terms of mean, relative standard deviation etc. must be
presented clearly
Conclusions- This section should summarize your main results and include some comments on
possible sources of error.
