Product Details

College Level Classic General Chemistry Experiment Students select the appropriate indicators for two titrations—a weak acid solution titrated with a strong base solution and a weak base solution titrated with a strong acid solution. The indicators are added to the solutions and the students perform the titrations. Titration curves of pH versus volume of titrant are generated and used to verify the appropriateness of the selected indicators. Students gain valuable experience with the process of titration using indicators and pH meters. An excellent assessment of student understanding of the principles of acid–base chemistry. Complete for 24 students working in pairs.
