Which one of the following is an attribute for an extracting solvent?
a. the extracting solvent should not be volatile
b. the extracting solvent should be non-toxic and readily available
c. the extracting solvent should would react with the solute
d. the extracting solvent should be miscible with water

The answer is B

[The extracting solvent should be non-toxic and readily available]

Explanation:

The extracting solvent should not pose a risk to life (or the risk have to be minimum) and be available in large quantity.

A. Most of the extracting solvents are volatile, and is a good think because you can remove them by distillation.

C. The extraction solvent should not react with the solute, because you lose the extracted compound.

D. The extraction solvent should not be miscible with water. Usually you extract compounds organic compounds from water using an appropriate extracting solvent.
