Question

In a UV-Vis spectroscopy experiment, why might a chemist choose to measure absorbance rather than percent transmittance?

Accepted Answer

Absorbance is directly proportional to concentration, making it easier to analyze.

Answer

Absorbance is less affected by sample impurities.

Answer

Percent transmittance provides more detailed spectral information.

Answer

Percent transmittance is more accurate for low concentration samples.
