Question

Sometimes when performing a crystallization, one solvent alone will not work and you have to use a solvent-pair. will the solvent pair pentaine and water work? why or why not?

Answer 1

Whether the solvent pair pentane and water will work for crystallization depends on the solubility of the compound being crystallized. Pentane is a nonpolar solvent and water is a polar solvent, so if the compound is polar or ionic, the solvent pair may work well.

Step-by-step explanation:

When performing a crystallization, sometimes a single solvent is not sufficient, and a solvent-pair is required. Whether the solvent pair pentane and water will work depends on the solubility of the compound you are trying to crystallize. Pentane is a nonpolar solvent, while water is a polar solvent. Nonpolar solvents are effective at dissolving nonpolar compounds, while polar solvents can dissolve polar and ionic compounds. Therefore, if the compound you are trying to crystallize is polar or ionic, the solvent pair of pentane and water may work well.

Answer 2

Answer: No, these two solvents cannot be used as a solvent pair.

Step-by-step explanation:

Crystallization: It is a process in which a compound is soluble in liquid from which it is to be solidified as a precipitate.

For crystallization process, the two solvents used should be miscible otherwise, there is no use of using them.

In this case, the solvents given are water and pentane and their miscibility with each other is very far away. Water has very high polarity than pentane.

Therefore, water/pentane system will not work as a solvent pair.
