Innovating Science® - Properties of Antacids

Properties of Antacids

Product # IS9352

With the global population spending over a half a billion dollars a year on commercial antacids, several companies are out there competing for a part of the business. In this activity, students will learn about some of the more common active components in over-the-counter antacids as well as investigate the rate of acid neutralization of five different antacids. Students will also compare the buffering ability of three different calcium carbonate based antacids. All antacid samples are included and the kit contains enough materials for 15 groups. Teacher's Manual and Student Study Guide copymasters are included.
