Question

Which is TRUE for spectroscopy of a mixture?

  A.

The absorbance for a mixture at a particular wavelength is the sum of the absorbances for the components that absorb at the particular wavelength.

  B.

Spectrophotometers can differentiate between mixture components that absorb at the same wavelength.

  C.

Each component in a mixture has the same molar absorptivity at the same wavelength.

  D.

The concentration for each component in a mixture is easily calculated by least squares for guesses of each component when the individual spectra are well resolved.
