Preparation of a Buffered Solution Kit

Addresses AP® Chemistry Big Idea 6 and Learning Objective 6.18. Prepare buffer solutions of assigned pH values and determine the buffer capacity of these solutions. Students determine how to prepare the stock solutions, how to mix the stock solutions to create a buffer solution of desired pH, and test the buffering capacity of their buffers. Provides a thorough experience in buffers; teach the experiment as either a guided activity or an inquiry activity. For 30 students working in teams of 3.
