Gizmo of the Week: Titration
Titration is a common lab method used to determine the concentration of one material that is dissolved or mixed within another.
During the process of titration, a chemist slowly adds an acid (or base) solution of known concentration to a base (or acid) solution of unknown concentration, called the analyte. An indicator changes color when the analyte is neutralized, and the concentration of the analyte can then be determined.
With the Titration Gizmo, students learn to calculate pH and explain the shape of titration curves. Students use titration to determine the concentration of an acid or base and explore titration of weak acids and bases, too.
After practicing with the Gizmo, your students will become whizzes at titration in no time!
