Carolina Investigations for Use with AP Chemistry: Analyzing Reaction Rates with Calcium Carbonate Kit

Product Description

Investigate how macro factors affect the reaction rate between solid calcium carbonate and hydrochloric acid. Teach this laboratory using the guided activity or the inquiry activity. In the guided activity, students vary the concentration of hydrochloric acid while the mass of calcium carbonate stays the same. In the inquiry activity, teams introduce new variables into their design such as the surface area, temperature change, or a catalyst. By analyzing the volume of reaction product carbon dioxide produced over time, students learn how the changes affected the reaction speed. Materials are sufficient for 30 students working in pairs. Both activities include assessment questions that follo…
