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.

Fill in the following blanks. As the dye concentration increases, the absorbance of the light [linearly increases, linearly decreases, exponentially increases or exponentially decreases]. The dye concentration units are [molar (M), millimolar (mM) or grams per liter (g/L)] . Although most people wrongly conclude that absorbance has units nm, in fact, absorbance is unitless. This is because it results from a ratio of light through a colored sample relative to light intensity through a clear (blank) sample. The units for the slope of the graph would be [mM, 1/mM or nm] . Hint: the slope is the change in y values divided by the change in x values. The units for the y-intercept of the graph would be [nm, nM or unitless] . The value for the slope of the line that describes the absorbance data is [6.4597 or 0.0008] The value for the y-intercept of the line that describes the absorbance data is [6.4597 or 0.0008] .
