Classic AP Requirement #19—Preparation and Properties of Buffer Solutions

In this laboratory, students investigate the properties of buffer solutions. The students make two ideal buffer solutions, one consisting of a weak acid and its conjugate base and the other, a weak base and its conjugate acid. The initial pH of each solution is determined. Strong acid and strong base are then added to each buffer in a series of steps, with the pH determined after each addition. The resulting pH values after each addition are compared to calculated values for each buffer. A challenging lab to test students’ understanding of pH and buffer chemistry.

Complete for 24 students working in pairs.
