Worked Solution & Example Answer:What is the purpose of the flame in atomic absorption spectroscopy (AAS)? (A) To ionise the sample (B) To produce a spectrum (C) To atomise the substance (D) To provide the absorption wavelength - HSC - SSCE Chemistry - Question 2 - 2013 - Paper 1
Step 1
To atomise the substance
Answer
In atomic absorption spectroscopy, the flame serves a crucial role in atomising the substance being analyzed. This means that the flame generates sufficient heat to break down the sample into its individual atoms. This atomization process is essential for the subsequent absorption of light by the atoms at specific wavelengths, which enables the quantification of elements in the sample. Therefore, the correct answer to the purpose of the flame in AAS is (C) To atomise the substance.
