extraction lab:
suppose that aqueous and organic (diethyl ether) layers were not mixed thouroughly
predict the effect that this would have on the results
in your answer, consider melting point temperature of benzophenone
thx
You will get a low melting point
If the aqueous and organic layers were not mixed thoroughly during an extraction in the extraction lab, it would likely have an effect on the results. In the case of benzophenone, the effect would mainly be observed in the determination of its melting point temperature.
During an extraction, the aim is to transfer a solute (in this case, benzophenone) from one solvent (the aqueous layer) to another solvent (organic layer - diethyl ether). If the layers are not mixed thoroughly, it means that the benzophenone may not be completely transferred to the organic layer, leading to an incomplete extraction.
When it comes to determining the melting point temperature of benzophenone, the purity of the compound is crucial. If the extraction is incomplete due to poor mixing, the benzophenone in the organic layer may contain impurities from the aqueous layer. These impurities can affect the observed melting point of benzophenone, causing it to deviate from its expected value.
Therefore, if the aqueous and organic layers are not mixed thoroughly during the extraction, it could lead to a lower purity of benzophenone in the organic layer, resulting in a lower melting point temperature compared to its known value.
To avoid this issue, it is important to ensure thorough mixing of the aqueous and organic layers during the extraction process to maximize the transfer of the solute from one layer to another and obtain accurate results.
