23. How do you set up and solve absorbance problems like this?
Which of the following is the reason that a more concentrated dye solution absorbs more light than a less concentrated solution? There are fewer molecules of dye in solution that can absorb photons, meaning more photons reach the detector, increasing absorbance. There are more molecules of dye in solution that can absorb photons, meaning fewer photons reach the detector, increasing absorbance. There are more molecules of dye in solution that can absorb isotopes. There are more molecules of dye in solution that can absorb electrons. There are fewer molecules of dye in solution that can absorb electrons, meaning more electrons reach the detector, increasing absorbance.
What procedures are utilized in optical analysis to determine a solution's concentration based on colorimeter absorbance measurements?
Why do we need to prepare a standard curve before we can use Beer's Law to determine the concentration of a solution? O We don't have to create a standard curve so long as we choose the appropriate wavelength. Because the standard curve tells us the absorbance of our sample Because the standard curve is used to determine the extinction coefficient Because the standard curve indicates what wavelength to set the spectrophotometer to
This absorbance value (no wavelength where the maximum absorption occurs) corresponds to what % Transmittance value?
