These simulations require flash to be activated in your browser and they are sourced from the Internet Archive Site, https://archive.org. At some point, many of these simulations will be available in non-flash form from the University of Oregon Chemistry Department website, but those are currently in development.

1. Acid Base pH Titration.
Click Image to Enlarge		Acid-Base pH Titration Chemistry Tutorial: For this tutorial you will compare the pH at various points during the titration of a strong acid vs. strong base to the pH at the same points during the titration of a weak acid vs. strong base. You need to do the calculations. Activity 1. GOTO the computer simulation and select "Strong Acid vs. Strong Base". Click fill the buret with Base. Select HNO3 as the acid and KOH as the base. Select an indicator. The computer will automatically assign you a molarity for the acid and a volume for the acid. Activity 2. GOTO the computer simulation and select "Reset". Select "Weak Acid vs. Strong Base". Click fill the buret with Base. Select CH3COOH as the weak acid and KOH as the base. Select an indicator. The computer will automatically assign you a molarity for the acid and a volume for the acid. Activity 3. Compare the amount of 0.200 M KOH needed to neutralize 50.0 mL of 0.200 M HNO3 with the amount of 0.200 M KOH needed to neutralize 50.0 mL of 0.200 M CH3COOH. Is the volume of KOH more, less, or the same? Explain and or show.  SEE MORE
2. Measuring the pH of Acid Solutions Using the pH Simulation.
Click Image to Enlarge		PH Meter: Measuring the pH of Acid Solutions Using the pH Simulation Chemistry Tutorial: The computer simulation will allow you to test the pH of different concentrations and volumes of acid and base solutions. Before doing anything with the simulation, please answer the following questions. Work in groups of three. When you have completed a problem or activity, explain your answers to your teacher. 1: Identify the following solutions using one of these terms: strong acid, weak acid, strong base, weak base, acidic salt, basic salt, or neutral solution. 2: If we change the pH of a HCl solution from pH = 6.00 to pH = 3.00. By what factor does this change the concentration of [H3O+] in the solution? 3: Which solution has the highest pH (largest number)? Which has the lowest pH? Activity 1. This activity will help you get use to using the computer simulation. Use a web browser on your computer to access the URL for the computer simulation. At the bottom right-hand corner of the page select acid solutions. Select HCl. Use the slider bar or type in a number to select a concentration, in units of molarity... Activity 2. Compare the pH of 100.0 ml of 0.500 M HCl pH = _____________ to the pH of 100.0 ml of 0.0500 M pH = ________________. Does this seem right to you? Activity 3. Compare the pH of 50.0 mL 0.500 M nitric acid, HNO3 (aq) pH = ______________ to the pH of 50.0 mL 0.0500 M nitrous acid, HNO2 (aq) pH = _____________________. Does this seem right to you? Activity 4. Use the computer simulation to design a series of experiments that will allow you to compare the pH of a weak acid to a strong acid using concentration of the acid as written on the label of the bottle (the initial concentration) as a variable. You will need to choose at least 5 different initial concentrations of [H3O+]. Plot a graph to show a relationship between initial concentration of [H3O+] (M) and pH. Before you do your experiment on the computer simulation explain your experimental design to your teacher.  SEE MORE
