Antacid Study Kit

Antacid Study Kit
SCIENTIFIC CONCEPTS/PROCESSES
Relate science to the real world by reinforcement and application
Perform a neutralizing activity and quantify it
Infer which brands of antacids are most effective
Determine cost-benefits of various brands
This Lab-Aid makes science more interesting and meaningful by dealing with fundamental chemical principles and applying them to products found at home.
Most antacids are composed of bases or alkalizing agents. Students are able to take actual over-the-counter antacids (Rolaids, Mylanta, etc.) brought from home and perform a neutralizing activity which determines how much acid can be neutralized by a particular brand. After conducting the activities, students make comparisons and draw conclusions about the different brands tested.
This kit is complete for 30 students.
Note: This kit does not contain antacids; they must be supplied.
