Question

1.(2 pts) What color photon is absorbed by a solution that appears yellow? 2. (2 pts) What is the color of a solution if it absorbs photons with a wavelength of 615 nm? 3. (2 pts) In the Beer-Lambert Law for an analyte solution which variable changes as the wavelength is changed? a) analyte concentration b) cell width c) molar absorptivity d) Plank's Constant e) molar mass of the analyte 4. (2 pts) Why must the Absorbance be blanked every time the wavelength changes? (molar absorptivity changes when wavelength changes)

Explanation / Answer

The observed color is said to be complement of the color absorbed.so,when blue violent is absorbed,yellow color appears At 615 nm, it shows orange colour In Beer lamberts law,wavelenth changes with molar absorptivity Absorbance is going to be very low in dilute solutions
