Detection of Ions of An Ionic Compound Lab Report

1. Limit the number of slides.  You should have between 8 to 10 slides.  Plan your slide layout and organize your information. 

2. You are welcome to show pictures and graphs in the presentation. Make sure you cite your outside sources at the bottom of the slide (not at the end).

3.  You can either record your PowerPoint presentation using slideshow record function or use the “Notes” section in PowerPoint to type out the scripts you would say for each corresponding slide.  Here is also a link showing you how to use PowerPoint to record:

4. The narration should be clear and coherent.  Do not just read each slide but have extra added information to present in your narration.  The notes should also include the extra information.

5. Use the rubric attached to this assignment to construct your presentation.  Make sure you do not treat each slide as a Q&A session.  The presentation has to flow from slide to slide.  

6.  I added some tips to help you create your presentation and expect you to use them when preparing your slides. You can find the page in the module section, and it is also linked here, titled “Tips to Create a PowerPoint Presentation“.

Pts

Describe what is the objective of this lab and theories you will be using. For each theory, use at least
2 chemical compounds to support your explanation. Concepts you must include:
1. Ionic compound and its solubility
2. Ionic compound and its conductivity
3. Flame test
4. Precipitation reaction
(2 pts each)

 

8.0 pts

Qualitative Techniques

Describe:
1. what materials and devices you will need to identify unknown salts based on conductivity
2. solubility
3. flame test.
How can these three methods help you identify unknown salts?

 

5.0 pts

Quantitative Techniques

Describe:
1. how to set up a vacuum filtration
2. how to use centrifuge.
(You will need to show the set up of the two techniques.)
3. the concept of titration
4. how to use titration to determine the amount of unknown substance.
(Show the set up of titration.)

Design your experiment

Pick a salt from the following list: calcium chloride, sodium nitrate, ammonium sulfate, ammonium chloride, magnesium sulfate, calcium nitrate, sodium acetate, sodium carbonate, sodium oxalate, barium chloride, and silver nitrate.
Discuss how would you confirm the identify of the salt using at least three methods you learned in this lab to support your rationale. (4 pts)
Discuss how would you quantify the amounts of salt you picked using the suitable method you learned in this lab. (4 pts)
