Molecular Titration

Published on 07/15/2011

Activity Overview

In this lesson, students explore a simulation of a pH titration that includes a molecular view of the chemical changes that occur as a strong base (NaOH) is added to a beaker containing a strong acid (HCl) solution.

Objectives

  • Students will observe what happens during a titration of a strong acid with a strong base, using a simulation accompanied by a molecular view and pH graph.
  • Students will determine the volume of base needed to reach the equivalence point.
  • Students will see how pH is related to an excess of H+ ions or an excess of OH– ions in a solution.

Vocabulary

  • acid dissociation constant
  • aliquot
  • concentration
  • equivalence point
  • pH
  • strong acid
  • strong base
  • titration

About the Lesson

This lesson features a simulation of a pH titration that includes a molecular view of the chemical changes that occur as a strong base (NaOH) is added to a beaker containing a strong acid (HCl) solution.
As a result, students will have a better understanding of:

  • The nature of strong acids and strong bases.
  • The chemical species present before, after, and at the equivalence point.
