Q. In UV-Vis spectroscopy, what does a higher absorbance value indicate?
A.
Lower concentration of the analyte
B.
Higher concentration of the analyte
C.
Higher wavelength of light
D.
Lower path length of the sample
Solution
A higher absorbance value indicates a higher concentration of the analyte, according to Beer-Lambert law.
Correct Answer:
B
— Higher concentration of the analyte
