Using Polar Solvents: Desorbing NO2 from Solid Adsorbent
What solvent would be suitable to desorb NO2 from the solid adsorbent in the sampler?
Based on the fact that NO2 is a polar molecule, explain your reasoning for choosing the solvent.
Suitable Solvent: Acetone
A suitable solvent to desorb NO2 from the solid adsorbent in the sampler is acetone.
NO2 is a polar molecule, meaning it has a partial positive charge on one end and a partial negative charge on the other end. To desorb NO2 from the solid adsorbent, a solvent with similar polarity would be effective.
Acetone, also known as propanone, is a polar solvent due to its molecular structure and the presence of a carbonyl group. It has a high polarity and can effectively interact with polar molecules like NO2.
Acetone's polarity allows it to form favorable interactions with the polar NO2 molecules, breaking their adsorption bonds with the solid adsorbent. Additionally, acetone has a low boiling point, which makes it convenient for desorption processes as it can easily evaporate, leaving behind the desorbed NO2 molecules.
Overall, acetone is a suitable solvent for desorbing NO2 due to its polarity and compatibility with polar molecules.
