Challenge Problems
Push your limits with challenges.
Question 1
A student measures the absorbance of a series of dye solutions and finds an absorbance of 0.650 with a path length of 1 cm. If the molar absorptivity is found to be 150 L mol⁻¹ cm⁻¹, what is the concentration of the dye in mol/L?
💡 Hint: Apply the formula directly.
Question 2
Discuss the implication of using a sample that exceeds an absorbance of 2.0 in UV-Visible spectroscopy. What might happen and how could you adjust your measurements?
💡 Hint: Think about how too much light might not be accurately measured.
