ASSESSMENT
1.1
Assignment 1[50]
Assignment question:
Find a complete report on any university second year physical chemistry laboratory experiment,
i.e., which contains the background of the experiment, the experimental procedure, and the
results obtained. Study the report and then based on the laboratory work performed write an
experimental report. The format of your report must follow the description in the provided below.
You must include the source of the report in the references.

Assignment Format and Marking Rubric
Date:
Title [1/1]: In the square bracket are the assigned marks.
When writing your assignment 1 (Lab report) make use as well of the tutorial letter 101 in
which the structural elements of a lab report are presented. This document must allow the
reader to repeat the experiment reported. The title tells the reader in a f ew words the
purpose of the experiment.
Abstract [4/4]:
This section summarizes the entire report and is written last of all. It is advisable at this
level to formulate a coherent narrative from summarizing sentences of each section. You’ll
improve on this approach with time.
Introduction [20/20]:
The main questions you intend to answer in this section are: What is the theoretical
background of the experiment? How do you intend to carry out the experiment?, and Why
is it important to carry out this experiment? Literature sources are required when
completing this section and they are listed in the bibliography section which concludes the
document. The high rating of this section stems from the detail each question involves.
Many questions and answers emanate from this section, hence adequate attention must
be given to writing it.
Methodology [5/5]:
This section describes step-by-step the process of collecting data. It is often entitled
experimental because it entails the details of carrying out the experiment. All materials
required in carrying out the experiment, which includes chemicals, equipment and the
manufacturers etc are listed in this section. The procedure must be complete.

Results [10/10]:
All data collected in regard to the experiment are provided in tabular form, and in correct
significant figures and units. Note that all measurement of physical quantities is attended
by error, which is estimated from the graduation of the measurement scale. The error must
be reported with the numerical value of the measured physical quantity. Any required
calculations are provide here. One detailed example demonstrating the calculation of
tabulated values is enough. Graph work appears in this section in proper graph paper.
Straight lines are expressed in terms of least squares linear regression.
Discussion and Conclusion [5/5]:
Observations about your experiment and factors affecting your results are discussed in
this section. You might have observed an unexpected trend in your values and have an
idea you wish to put forward about the possible source and possible corrective measures.
