  Activity: Simulation Activity: Acid-Base Titrations Mark as Favorite (2 Favorites)

  In this activity, students will use a simulation to collect titration data to determine the concentration of a strong acid or a strong base. Multiple practice opportunities exist, as each time the simulation is reset, a new value is generated for the unknown concentration. The simulation is not designed to be used in place of the lab technique, but rather as a way of strengthening the skills already learned in the lab.

  Activity: Simulation Activity: Acid-Base Titrations (AP) Mark as Favorite (3 Favorites)

  In this activity, students will interact with a simulation to practice calculating values from titration data. AP level students select an analyte from a list of weak and strong acids and bases. A pH vs. volume curve is generated using randomized values for the titration, and students use the trace function on the graph to identify the appropriate data points for calculating the concentration and, for weak acids or bases, the value of Ka or Kb, for the selected analyte. The simulation is not designed to be used in place of the lab technique, but rather as a way of strengthening the skills already learned in the lab.
