During the liquid-liquid extraction of your panacetin sample, the dissolve acetylsalicylic acid (aspirin) will be in which layer

Then, as mentioned, aspirin is placed in the second layer.

Explanation:

Liquid-liquid extraction is a very useful method to separate components from a mixture. It consists of separating one or several substances dissolved in a solvent by transferring them to another insoluble, or partially insoluble, solvent in the former. The transfer of matter is achieved by direct contact between the two liquid phases.

Panacetin is a mixture of sucrose, aspirin and tylenol, whose densities are respectively are 1.59 g / mL, 1.4 g / mL and 1.26 g / mL.

For the extraction process, the solution is arranged in a separating or separating funnel, an organic solvent immiscible with water is added (ethyl ether is the most used), the solution with the compound to be separated, the funnel is covered and the funnel is covered. shake According to the solubilities and density different layers are observed. The denser the compound, the more it will sink. Therefore, the upper layer is tylenol, followed by aspirin, and the lower layer is sucrose. Subsequently, by separating the separating funnel, the phases are separated.

Then, as mentioned, aspirin is placed in the second layer.
