Solution Chemistry
Housekeeping: We are now investigating solution chemistry for the next couple of weeks and then move into some basic physics. Solution chemistry is very easy.
Agenda:
1. Intro to solution chemistry
2. The solvation process

Mission 1: The Problem is the Solution
Mission Objectives. You should be able to:
1. Define these terms: solution, solute, solvent, soluble, insoluble, miscible, and immiscible.
2. Provide examples of solutions in all three states of matter.
3. Define "solubility" and explain the factors that affect it.

Mission 2: SOLVATION, Y'ALL!!!
Mission Objectives. You should be able to:
1. Describe the process of solvation.
2. Compare and contrast the solvation processes between ionic compounds and covalent compounds.
3. Identify the factors that affect solvation.
4. Define and explain the following terms: unsaturated, saturated, supersaturated, concentrated and dilute.
Use the awesome Tyler DeWitt to help you with the Mission objectives.

This video goes into detail about saturated solutions. Be sure you can distinguish between the three.
Here is a marvelous powerpoint that talks about the solvation process and solubility.
Here is the lab we will do in class.

This semester's research project, which will be graded under Criterion D, is an investigation into a food-borne illness. You will have some time in class to research the topic. You and one other person will research one of the following food-borne illnesses and present your research to the class.
Salmonella
Clostridium perfringens
Staphylococcus
Clostridium botulinum
Listeria
Shiga toxin-producing Escherichia coli
Hepatitis A
Trichinosis
Gastroenteritis
Tapeworm Infection
Outline your paper according to the following:
I. Introduction. Define and discuss food-borne illnesses in general terms. End your intro with a statement about which illness your paper will focus on. This is your thesis statement.
II. Body paragraph 1. Introduce your illness. How do patients contract it? How long does it last? What are the symptoms and side effects? Provide examples.
III. Body paragraph 2. Discuss how the illness is treated. Provide examples.
IV. Conclusion. Summarize the paper. Evaluate the research that you have examined and discuss the its implications. Do you believe that your food-borne illness will eventually be eradicated or not? Why?
Your presentation has two components: a 2-page essay and a class presentation. I will distribute rubrics so that you have a format to follow. Presentations will take place ____________. A rough draft of the essay is due _____________. Final drafts are due __________________.
Go HERE to complete a summary lesson on solutions. There are some topics we have not covered completely, but you should be able to research and find the answers. You WILL NOT complete the entire packet. I will tell you exactly what you should do: You will complete numbers 1, 2, 3, 4, 7, 11 and 12. You will find most of the answers on pages 2 - 4 and 20 - 23. You can research the rest of the answers.
