1 Acid/Base Interactions Name Lab Section Log on to the Internet. Type the following address into the location-input line of your browser: This will load a Particulate Simulation. Once you have the simulation running your screen will look like what is shown in Figure 1 below. If you haven t already done so, read the Particulate Simulation section of the Introduction to MoLEs Activities to learn how to use the simulation. Figure 1. 1
2 Problem Statement: How do acids and bases interact? I. Data Collection: A. The simulation represents the strong acid HG when it is added to water. Allow the acid and water to interact by clicking on the Resume and Enable Reactions buttons. Describe what happen when the acid dissolves in the water. Use the Replay function in the drop down menu and the tracking button to aid your observations. Write a balanced equation to represent the interaction. What chemical species are present when the interaction is complete. B. Pause the simulation. Add 1.00 mole of OH - to the reaction container. Based on what you observe in the sample region and control bar region of the screen, calculate and record the initial concentration of each substance present in the following table. Click on the Resume button. Allow the simulation to run until no more changes occur. Click on the Pause button and calculate and record the ending concentration of each substance present in the following table. Calculate and record the change in concentration for each of the substances. Initial - I -- Change - C -- Ending - E -- [H 2 O] [HG] [H 3 O + ] [G - ] [OH - ] C. Add an additional 1.0 mole of OH - to the reaction container. Click on the Resume button and observe the interactions between the reactant particles. Use the Replay function in the drop down menu to aid your observations. Describe what happened when the reactant particles interacted with each other. What interactions cause changes to occur and what interaction don t cause changes to occur? 2
3 II. Data Analysis and Interpretation: A. Write a balanced chemical equation for the reaction you observed in section I. B. and C. of this simulation. B. How did you decide when the reaction was complete in section I. A.? C. How did you decide when the reaction was complete in section I. B. and C.? III. Data Collection: A. Type the following address into the location-input line of your browser: This will load the Graphic Simulation for the reaction you studied in the previous sections of this activity. If you haven t already done so, read the Numeric Simulation section of the Introduction to MoLEs Activities to learn how to use the simulation. 3

Describe what happen when the acid dissolves in the water. Write a balanced equation to represent the interaction. What chemical species are present when the interaction is complete. C. Pause the simulation. Add 1.50 mole of OH - to the reaction container. Based on what you observe in the control bar region of the screen, calculate and record the initial concentration of each substance present in the following table. Click on the Resume button. Allow the simulation to run until no more changes occur. Click on the Pause button and calculate and record the ending concentration of each substance present in the following table.

C. write a chemical equation representing the reaction you are studying. B. What is the reacting capacity of this acid? (i.e. How much base is necessary to react with a specified amount of acid.) 4
5 C. What role does the water in the reaction container play? (What does the water do in the reaction?) D. Discuss the change in concentration for each of the substances in the reaction.

Write a balanced equation to represent the interaction. What chemical species are present when the interaction is complete. 5
6 B. Pause the simulation. Add 1.00 mole of OH - to the reaction container. Based on what you observe in the sample region and control bar region of the screen, calculate and record the initial concentration of each substance present in the following table. Click on the Resume button. Allow the simulation to run until the reaction is complete. Click on the Pause button and calculate and record the ending concentration of each substance present in the following table. Calculate and record the change in concentration for each substance. I -- C -- E -- [H 2 O] [HB] [H 3 O + ] [B - ] [OH - ] C. Add an additional 1.00 mole of OH - to the reaction container.
