      General Instructions

      In this activity, you will describe the general properties of aqueous solutions, precipitation reactions, acid-base reactions, and oxidation-reduction reactions. You will also calculate the concentration of unknown solutions using titration. To successfully achieve this, you will need to review all the study materials for Module Three.

      Step 1: Select and Reflect

      Select one of the following lessons below and reflect on how they are applied in practical settings.

      • General Properties of Aqueous Solutions
      • Precipitation Reactions
      • Introduction to Acid-Base Reactions
      • Introduction to Oxidation-Reduction Reactions
      • Concentration of a Solution

      Step 2: Respond

      Using supporting data to back your arguments, prepare a 350-500 word written piece which discusses any one of the following:

      • How can you use electrochemical methods to identify the presence of electrolytes in a solution accurately?
      • Describe the predictive models that can be used to determine the solubility of ionic compounds in water.
      • What is the Henderson-Hasselbalch equation, and how is it used to calculate the pH of a buffer solution?
      • Describe what species gains electrons in an oxidation-reduction reaction, what happens when zinc metal reacts with hydrochloric acid, and what is said to be oxidized in an oxidation-reduction reaction.

      Step 3: Share 

      To share your work, click on the “Add a new discussion topic” button under this post and paste your work into the “Message” box. Make sure to reference others’ intellectual property when necessary. All references should follow 7th Edition APA formatting. For further instructions, see the resource on the Himmelfarb Health Sciences Library: APA citation resource (N.B.: references are excluded from word counts).

      Step 4: Interact 

      To complete the activity, evaluate and categorize the work from one of your peers based on items A - E of the rubric below. Provide a rationale for the grade you have provided, as well as comments or suggestions for improvement. To post a reply, click “Reply” on a particular discussion, write your feedback and then click on “Post to forum.” You can use the list below as an example:

      Item A is  .…. because….  My suggestions for improvement are….
      Item B is  .…. because….  My suggestions for improvement are….
      Item C is  .…. because….  My suggestions for improvement are….
      Item D is  .…. because….  My suggestions for improvement are….
      Item E is  .…. because….  My suggestions for improvement are….

      OPTIONAL Step 5: Interact (10 minutes)

      If you would like to, you can reply to your peers' posts in a respectful and professional manner. Ensure that your post engages your peers' ideas by including a reflection on their comments, sharing ideas of other potential difficulties and parties involved, or asking thought-provoking questions. If a peer comments on your posting, please reply. To post a reply, click “Reply” on a particular discussion, write your feedback and then click on “Post to forum.”
