Emission spectroscopy is used for__________________?
Correct answer: B. Solids and metal analysis
- A. Determining water purity
- B. Solids and metal analysis
- C. Determination of CO2 in gases
- D. NOx determination
Explanation
Emission spectroscopy identifies elements from the characteristic wavelengths emitted by excited atoms, so it is widely used for elemental and metal analysis in solids. It is not primarily a general method for water purity, carbon dioxide, or NOx measurement in the form stated.
