Question

When is an extraction employed?

Expert Solution

Step 1

A solvent extraction (or liquid-liquid extraction) is an analytical extraction technique.

Step 2

This is employed when a compound is soluble in two different solvents- one polar and the other non-polar solvent, i.e., the two liquids must be immiscible with each other. The substance is relatively soluble in the two solvents, which is the basis for its separation.
