Post Laboratory Questions:
Please answer the following questions on a separate sheet(s) of paper. You may
neatly handwrite or type your responses. They will be collected at the beginning
of the next laboratory period. Late responses will receive half-credit.
Part A:
Use the data collected using 4-t-butylphenol, draw a graph of the retardation factor vs.
solvent composition. Interpolate the data points (i.e. draw a smooth line through them).
Is the relationship between Rf and solvent composition linear? Suggest a reasonable
explanation for your results.
A student identified some white crystals located in an unlabeled flask that his lab partner
had just purified via chromatography. Based on his partner's lab notes, he is certain that
the unknown is only one of two known compounds, 4-t-butylphenol or 1,4-
dimethoxybenzene. In the space below, describe a simple experiment that would allow
the student to determine the identity of the unknown.
Part B:
Calculate the weight percentage of ferrocene and acetylferrocene in your metallocene
mixture using the data collected.
Part C:
In today's experiment, a chromatographic purification of multiple organic compounds
was performed. Based on your experience, which of the following physical properties
(boiling point, density, solubility, or melting point) do you think causes/allows
chromatography to work? Explain your reasoning.
Calculate the weight percentage of fluorene and fluorenone in your mixture using the
data collected.

CSI Part 4 - Making the Case!
Assignment RequirementsYou have analyzed and scrutinized the evidence, so now it is time to make your case as the prosecutor! First, you need to decide who to prosecute for the murder of Chelsie Vapolt. Then, you will write a legal brief that utilizes the facts and evidence from the case to make an argument for why the defendant is guilty beyond a reasonable doubt.This legal brief should contain the following elements: Your hypothesis for the case. The hypothesis should clearly state who the defendant is, the crime that they are being been charged with, and their motive. (Note: there can only be ONE defendant!)Possible charges include :Murder: Suspect intentionally killed the victim and planned out the entire crime beforehand.Intentional manslaughter: Suspect intentionally killed the victim in the heat of the moment. A crime of passion without forethought.Accidental manslaughter: Suspect accidentally killed the victim. The murder was unintentional. A narrative of the case -- You should provide a brief overview of the key facts of the case and a timeline of events, explaining how they support your hypothesis. You can utilize the timeline and character web diagrams that you developed in CSI week 1 as part of your narrative. (Make sure that you provide a text explanation for any diagrams that you include!) A discussion of the key evidence that supports your hypothesis. An effective brief will include multiple types of evidence from the case file, autopsy report, hair analysis, UV light testing, Kastle-Meyer blood test, and DNA analysis. Do not discuss every single piece of evidence that you analyzed for the case. Rather, you should select the key pieces of evidence that support your argument. To receive full credit, you must include a minimum of three different pieces of evidence. For each piece of physical or DNA evidence that you discuss, you should clearly and concisely explain the results of your analysis and how those results support your argument. Make sure you describe how the evidence fits into the larger narrative about your case. Rebuttal of the arguments that the defense could use to show reasonable doubt about the guilt of the defendant. Pick a minimum of two facts or pieces of evidence and describe how the defense could use them to bring doubt to your case. Explain how you would counter the defense's argument. To support their argument, the defense may utilize different pieces of evidence than you did or they may use the same pieces of evidence but provide a different interpretation.Your legal brief should be a minimum of 250 words, be well-organized and present a clear, convincing narrative of the case. Be sure to avoid arguments that rely upon emotions or are not supported by the evidence or facts of the case. Before you begin writing, I recommend that you review the previous CSI assignments as you will need to incorporate your findings from those assignments into your brief: CSI Part 1: Case File and AutopsyCSI Part 2: Evidence AnalysisFacts of the CaseSubmission GuidelinesThis assignment will be submitted via Turnitin.

WCU Chemistry Titration Presentation
The goal of your Signature Assignment is to show that you can compute properties of solutions and analyze and interpret data. You will create a PowerPoint presentation that shows the process of going through an acid/base titration like you would if you were in a physical lab.For the presentation:You will prepare a sample of an unknown acid to titrate using a known concentration of base. You will set-up a burette filled with a known concentration of base and use proper titration techniques to reach an end-point to the titration. You will then calculate the concentration of the unknown acid on your own.For Part I:Create a PowerPoint presentation (4-6 slides) that covers the lab scenario above.Include your thoughts on why understanding acid/base titration is important to your future career, and how you will use this concept as you complete your degree.Your presentation must consist of more than merely a series of bullet points to earn full credit.Use the Notes section for each slide to fully explain your answers.This assignment should be in current APA Style with both a title slide and a reference list that includes all of the sources used. At least two scholarly sources should be used (your textbook can be one of the sources).See rubric for specific grading criteria.This lab assignment presentation involves putting together a presentation to show other students on how to perform titration. In other words, your presentation can be used to show other students (next term) how they can perform a titration by following your instructions and calculations. To do this presentation, we are giving you the type of acid, acetic acid, the type of base, NaOH to be used, and you will use phenolphthalein as the indicator. You will use the data given to you to be used as an example of how to solve the mathematical calculations. At the end of your presentation, you will show the unknown concentration of the acetic acid (Molarity) and will also show the % mass/ vol of the Vinegar solution. Part 1Purpose of a titration, what is titration and why do we perform a titration?Instrumentation- what are the instruments, glassware used when performing a titration.Chemicals and Procedures. What chemicals are needed? List and explain the procedures for this experiment.Observations and expectations- List the observations and write your expectations. This might include color change and when the equivalence point (endpoint) might be reached.Part 2Calculations and Results. Show all your calculations and write your results, the Molarity of the acetic and the % of the acetic acid.Your instructor will provide guidance and examples for completing calculations for titration.This assignment should be in current APA Style with both a title slide and a reference list that includes all the sources used. At least two scholarly sources should be used (your textbook can be one of the sources).
