Question

1. Absorption bands tend to be broad as exciting wavelength changes:

UV-vis only

IR only

Both

Neither

2. Samples being prepared for atomic spectroscopy could be subject to AAS, AES, or AFS techniques. Choose between true or false for the following statements.

True or False? In AAS, samples are subjected to exciting light. The measurement that relates to concentration is concerned with the light that strikes a detector. The analyte absorbs some light in an excitation process.

True

False

3. Suppose two cations in a mixture are about to be analyzed with ion chromatography. Both are competing for negatively charged binding sites on a support. Would the cation with the higher selectivity coefficient have a longer or shorter retention time than the cation with a smaller selectivity coefficient?

Longer

Shorter

The Same

Neither

4. Volatilization, atomization, and ionization are all important processes to consider in atomic spectroscopy. Consider how energy is used in these three processes. True or False? Volatilization does not require energy to change non-gas samples into gas to enter flames. Atomization requires heat to turn compounds into atoms. Ionization uses energy to strip electrons from atoms.

True

False
