Elementary Analytical Chemistry

Purpose: By collecting the data, what question were you looking to answer? (Note that learning a technique is not the purpose of this lab. You collected numbers so that you could use them to arrive at an answer. What was the question?)
Theory: Describe the rationale behind this procedure. In your discussion, you should consider the suggested readings and suggested terms and topics in each lab.

Procedure: Give a brief description of your process. Remember that this is for someone who has not performed the experiment. Describe the apparatus and necessary steps.

Data: Provide Tables of Raw Data Collected for each device. No calculations have yet been performed on any raw data- this is exactly what the instrument provided, to the proper precision of the device.

If your data is better shown as a graph, display the graphed data here. Using the "Snipping Tool" in Windows or Apple screen shot that is cropped, cut and paste from your Excel plots to create figures in your report for plots and images. Caption each figure. (The snipping tool is used so that the curve-fitting and interpretation is preserved. If you cut and paste from excel, the graph markup is not preserved)

Sample Calculations:
Show an example of one of each of these. Show the formula that you used including all units and chemical species, show sample number substitution, then show your results: Use your equations template in Word to create these. Refer to the rubric and protocol for the expectation You may also include intermediate summary tables here if relevant.

Remember that Excel tables are not calculations- they are most similar to a calculator display of results.

Questions: Answer any directed questions not included in your results Error Analysis:

Question 1. Discuss procedural or sample handling errors that may have led to incorrect measurement. Whether these occurred or not, what error sources should be considered? What difficulties or sources of error did you have when performing the experiment?

Question 2. How do you think that your stated difficulties affected your resulting measurement?

Question 3. Were there any data that were rejected? On what basis?

Areas for Future Work: Consider how you may circumvent at least one of your stated error sources.

Results: Create a Summary Table in Word for the results of your final calculations, including pertinent statistical analysis. Using a narrative format, describe how your results answer the purpose.
