Challenge Problems
Push your limits with challenges.
Question 1
A solution shows an absorbance of 1.2 at a wavelength of 260 nm. If a known standard solution has an absorbance of 0.2 at the same wavelength for a concentration of 0.05 M, calculate the concentration of the unknown solution.
💡 Hint: Utilize the direct proportion between absorbance and concentration.
Question 2
If a sample absorbs UV light at 280 nm strongly, how would its absorbance change if diluted by half?
💡 Hint: Recall what happens to absorbance as concentration changes following linear relationships.
