Description
Purpose:
The purpose of writing a partial lab report for Redox Reactions experiment is to continue to familiarize you with technical scientific writing, data analysis, and its presentation.
Skills:
In this lab report you will:
- Analyze redox reactions from qualitative experimental data.
- Continue to improve your scientific writing by composing a portion of a formal lab report (title page, results and calculations section, discussion, and conclusion).
Knowledge:
This assignment will also help you to become familiar with the following important content information:
- Organize your data in a results and calculations section including:
- Writing balanced net ionic chemical equations.
- Apply vocabulary of redox reactions to the experiment.
- Create a partial activity series for Zn, Fe, Fe3+, I, Br, Cu, and H
- State and analyze your activity series in the discussion.
- Restate your activity series in the conclusion.
Tasks:
This exercise asks you to collect, organize, analyze, and evaluate data you collected in the lab. You will type a lab report that includes the following:
- Title page
- Results and Calculations section
- Table summarizing your major experimental results.
- Experimental observations
- Balanced net ionic reactions
- Element oxidized, element reduced, stronger oxidizing agent, and more active element.
- Discussion
- State your activity series.
- Analyze your experimental data:
- Did you have any difficulties determine the activity series?
- If so, what species are you unsure of the relative activities?
- What additional experiments might help you to make a better assessment of relative activities?
- State any sources of error. What affect did it have on your activity series?
- Conclusion
- Reiterate your experimental activity series using complete sentences.
- Table summarizing your major experimental results.
Criteria for Success:
We are building your report writing skills of organizing data, analyzing data, and summarizing data. Incorporate the feedback from your previously graded lab reports.
- As you write up your report:
- Be sure to summarize your major data in your results and calculations section, state and analyze your activity series in your discussion and reiterate the activity series in your conclusion.
- Make sure that your laboratory pages have the headers and footers completely fill out, and that your data and observations are complete enough for another student to use your lab notebook to complete the experiment.
-
- Before the start of lab on the due date:
- Upload your prelab and typed report to Canvas on time. Remember that practice make progress. The more that you practice scientific writing the better you are going to get at it. It is important to get timely feedback from your instructor on your lab reports by turning them in on time.
