Q: During atomic absorption spetroscopy, the concentration of certain atoms can be measured in very low concentrations. The absorption is tuned to the optimal absorption wavelength of individual metals. Will atomic absorption spectroscopy be useful for the measurement of ethanol in pure water?
A		Yes because a mixture of ethanol and water does not have metal ions
B		Yes because ethanol and water mixtures contain metal ions
C		No because a mixture of ethanol and water does not have metal ions
D		No because ethanol and water mixtures contain metal ions
