Ms. Keily’s period four and six class worked on a titration lab to model Structure 1 of their International Baccalaureate chemistry class.

Working together in groups of up to five people, students worked to neutralize an antacid tablet with hydrochloric acid.

Crushing up two different antacid tablets, the powder was then mixed with hydrochloric acid in separate beakers.

Junior Andres Betancourt slowly pours approximately 25 millimeters of hydrochloric acid into a beaker.

Referring back to their worksheet, junior Tiffany Beh and sophomore Alexander Ridoux work together to complete their experiment.

Upon boiling the the hydrochloric acid and tablet mixture, junior Anthony Marrero carefully lets three drops of phenolpthalein, a pH color indicator, flow into the mixture.
