How to Write a Remarkable Conclusion of a Chemistry Lab report
Some
students get confused when writing their conclusion part of the chemistry lab
report. They do not know what to include in a conclusion part of a lab report. Usually,
conclusion paragraphs consist of aims, main findings, explanations of results, and
sometimes suggestions for further study. The mentioned items should be written
in paragraph forms. However, it depends on the instructions of the particular
lab report. Start with restating the aim(s) of the lab report.
Subsequently
summarize your findings. You expound whether the data support the hypothesis
being tested or not. Explain how the experiment could be improved. Provide
further directions for future studies on the same topic. A sample of a
conclusion part of a chemistry lab report is provided below.
Sample
of a conclusion part of a chemistry lab report:
The
experiment aims at determining water of hydration and chemical formula of unknown
copper chloride. The chemical formula and water of hydration of unknown copper
chloride were determined by using concepts of mole ratio, conservation law of
mass and proportional law. Based on these concepts, it was established that the
chemical formula and water of hydration an unknown copper chloride was CuCl2.
2H2O.
Water
molecules coordinated with ionic compound (CuCl2) in ratio1:2. This
ionic compound (CuCl2) requires two molecules of water to form
copper chloride hydrate. When copper chloride hydrate is heated, it releases to
water of hydration in the form of water vapor, leaving behind anhydrous copper
chloride. Besides, when anhydrous copper chloride is dissolved in water, it
coordinates with water molecules forming copper chloride hydrate (a blue
solution).
When
the aluminum wire is placed in a blue solution of copper, it turns colorless.
This happens because aluminum is reactive than copper. As a result of this,
aluminum atom displaces copper ions from chloride ions, thus forming aluminum
chloride, which is a colorless solution. The present experiment could be
improved by using analytical grade reagents and avoiding using contaminated
apparatus. Further studies should concentrate on investigating the effects of
replacing aluminum with less reactive elements on a blue solution of copper.
Bottom
line:
This
experiment does not require testing of the hypothesis. For that reason, it is
not incorporated in this sample. Furthermore, different chemistry lab reports
have distinctive instructions. Therefore, the students should strictly follow
the provided instructions by their institutions for better marks in their
chemistry lab reports. You can request other parts of this lab report by leaving a comment below.
