Product Details

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. Materials Supplied: Acetic acid solution Ammonia/Ammonium chloride buffer solution Sodium hydroxide solution Sodium acetate solution Beral-type pipetsFlinn Transition Guide Available! Adapt this classic AP Chemistry experiment for guided-inquiry and correlate with the AP Chemistry curriculum framework with the Flinn Scientific Inquiry Guidance and AP* Chemistry Curriculum Alignment Guide.
