Question 1.
What is the principle behind Atomic Absorption Spectroscopy?
Show hintHide hint
Think about how light interacts with atoms.
Question 2.
Name the two atomization methods in AAS.
Show hintHide hint
Consider the environments in which atomization occurs.
3Question 3.
What does AAS stand for?
- Atomic Atomic Spectroscopy
- Atomic Absorption Spectroscopy
- Atomic Acid Spectrophotometry
Show hintHide hint

4Question 4.
True or False: AAS can be used to analyze gases.
- True
- False
Show hintHide hint
Consider the sample states that can be measured.
Question 5.
You are using AAS to determine lead concentration in a water sample. If the absorbance measured is 0.400 and the calibration curve provided a slope of 0.120 (Absorbance per ppm), calculate the concentration of lead in the sample.
