WebIn this experiment the iron content of an unknown will be determined by comparing the absorbance at a specific wavelength of an unknown solution to that of standards.

When a light beam encounters a material, radiation can be absorbed or reflected by the surface. Metals are known for having high reflectivity, which explains their shiny appearance. Since the reflectance of light by metals is high their absorption is low because the sum of both must correspond to 100% of the incident light. http://spiff.rit.edu/classes/phys314/lectures/bohrprob/spectra/iron.html h2a hilton head
