Meets AP Science Practices 2, 4, 5, and 6
- Addresses Big Idea 1
- Material provided for 30 students working in pairs
- Investigation includes updated literature aligned with new AP Chemistry curriculum standards
In this kit students will determine the concentration of blue dye in an unknown solution called Scienceade. A calibration line will be made with a known sample and this will be used as an aid in solving the problem. Students will need to justify the selection of a particular type of spectroscopy to measure properties associated with vibrational or electronic motions of molecules and they will design and interpret the results of an experiment regarding the absorption of light to determine the concentration of an absorbing species in a solution. Includes blue dye no.1 and Scienceade Stock Solution. Requires spectrophotometer or colorimeter, and cuvettes, available separately.
