Chemistry Lab Experiment Essay Example

Background Information and Research

1. Provide a simple explanation of paper chromatography and its applications. 2. List three practical uses of paper chromatography in the fields of chemistry and biology.

It is essential to provide citations for any research performed in this section.

Purpose

Clearly state the objective of this lab investigation in one or two sentences.

Enumerate all the materials used in this experiment.

Procedure

The lab procedure is described in a step-by-step manner.

Data and Observations

This section includes various elements such as original predictions, an organized data table with pigment components and distances traveled, and any additional observations made during the investigation. Two separate sections or tables are created for the solutions used (salt water and alcohol).

;">Discussion and Conclusion

In this part, the lab's observations and results are discussed along with any mistakes made or measures taken to avoid them. Suggestions for improvements in future labs' procedures are also provided.

The discussion section of this lab should also include discussions on the following:

• A comparison of how each solution (salt water and alcohol) separated the pigments from each color of candy or ink type.

• Which solution worked better at separating each of the pigments (it may be different for different candy colors or inks), and why do you think that is?
• If you had allowed less time for the lab (stopping the separation process when the solution was halfway up the paper), how do you think that would have affected your results?
• What pigment colors traveled farther up the paper? What pigment traveled the least?

Were the pigments in other candy colors or inks similar or different?Did they also hav
