Light Color and Concentration (Colorimeter Version)
If you’ve ever added a powdered drink mix to water, you realize that the more concentrated the drink, the deeper the color of the solution. Analytical chemists, particularly in the agricultural and medical fields, routinely use a quantitative approach called spectroscopy to determine the concentration of solute in a solution as it relates to the color of the solution.
Students learn how to use visible light to determine the concentration of colored ion species in a solution.
The student can design and/or interpret the results of an experiment regarding the absorption of light to determine the concentration of an absorbing species in a solution.
Sensors / Equipment Used:
Our PASPORT Colorimeter records all 4 wavelengths simultaneously--no need to guess at wavelength to get a quality measurement.
The Associated Bundle:
Contains the sensors and probes needed to perform all 17 experiments in the Advanced Chemistry Teacher Guide and all 25 labs in the Chemistry through Inquiry Guide.
