Investigating of pH and Conductivity during a titration of a diprotic acid

Activity Overview

In this investigation sulfuric acid will be added to a solution of Ba(OH)2 using a pH probe and a conductivity probe.

From this process the pH of first and second equivalence points will be determined along with mapping the conductivity during the titration process.

Before the Activity

Prelab:

Prepare 50 ml of 0.02 M H2SO4

Prepare 300 ml of 0.02 M Ba(OH)2

During the Activity

After the Activity

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
