NANSLO Remote Lab Activity: Beer-Lambert Law

This NANSLO lab activity is self-contained and can be used in first year general chemistry with lab and survey of chemistry courses. In this activity, known concentrations of nickel sulfate are used to create a standard curve and to determine the concentration of an unknown sample. The lab activity includes background information on the electromagnetic spectrum, the method for calculating the energy of a photon of electromagnetic radiation and the relationship between wavelength and frequency of electromagnetic radiation, and information on how the absorbance of a solution is related to the concentration of the absorbing species in a solution known as the Beer-Lambert law . The lab activity includes pre-lab questions, lab exercises, and data collection and analysis activities.
Microsoft Word NANSLO Remote Web-based Science Lab NANSLO Remote Lab Activity: Beer-Lambert Law uses a spectrometer to measure and analyze the visible light absorbance spectrum of several solutions and create a table from these observations, find the relationshio between absorbance and concentration of a specific solution, measure the absorbance of an unknown concentration of that solution, and calculate the concentration of the unknown solution using a standard curve. It contains pre-laboratory questions and laboratory exercises for the assigned lab. (3 MB)

Quality Note:
Curriculum experts in this discipline worked with others to define learning objectives needed for this lab activity. Draft activity was shared among faculty. Based on feedback, lab activity was modified prior to distributing as final. Experts in remote web-based science labs who are also science faculty worked together to define the web-enabled interface design used by students to perform the lab activity via the Internet and created the lab setup (robotics, scientific equipment, and items needed to complete the lab activity) testing it with lab technicians and others prior to launching the final lab activity.
Quality of Subject Matter was assured by:
  • Consultations during development of instructional materials
