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.
This experiment may require software and an interface for data collection.
