Concept explainers

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

Question

Using the trendline from your plot, calculate the absorption of a solution with a concentration
of Cr3+ of 0.0325 M. Hint, check your Excel plot to see if concentration is the x or y axis.
3.
Substitute as appropriate into the equation of the trendline.
