There will be 3 worksheets that need to be filled out, completely on the documents and sent back to me. Each one has a different link you will need to go to in order to run a simulation and answers the questions on the worksheets.
Worksheet #1: Creating a Buffer Solution
Step 1: Go to the Chem CollectiveLinks to an external site. website and watch the video walkthrough.
Step 2: Go to Virtual Lab: Creating a Buffer SolutionLinks to an external site. and play around with the simulation.
Step 3: Click on the "Buffer Creation Problem" button for additional information.
Step 4: Use the simulation to answer the problem below.
Scenario: The stockroom contains 1M NaAc (Sodium Acetate), 1M HAc (Acetic Acid), distilled water and strong acids and bases. You need to create a buffer solution that has a pH of 4.75 such that when 1 mL of 10 M HCl is added to 100 mL of your buffer, the resulting pH is 3.75 (+/- 0.1).
Question: What concentrations of HAc and NaAc do you need to create the buffer solution?
Step 5: Post a response on the discussion board with your observations.
Worksheet #2: Solution Dilutions (worksheet is attached below)
Step 1: Download the Concentration Simulation Worksheet Download Concentration Simulation Worksheet.
Step 2: Go to the concentration simulationLinks to an external site. website.
Step 3: Complete the worksheet using the simulation.
Step 4: Upload your completed worksheet
Worksheet #3: Chemical Kinetics
Step 1: Go to the Chem ReaX Virtual Lab: Chemical KineticsLinks to an external site. to access instructions and parameters.
Step 2: Go to the ChemReaXLinks to an external site. website to access the lab simulation.
Step 3: Run multiple simulations with parameter variations as needed to answer the questions from the ChemReaX Virtual Lab: Chemical Kinetics (step 1).
Step 4: Post your results on the discussion board.
