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
