Final answer:
Liquid-liquid extraction is the type of extraction that separates compounds based on solubility in a particular solvent. It uses two immiscible solvents to create separate aqueous and organic layers, allowing the compound of interest to partition between them.
Step-by-step explanation:
The type of extraction that separates compounds based on solubility in a particular solvent is called liquid-liquid extraction.
This method uses two immiscible solvents to create an aqueous layer and an organic layer, and the compound of interest partitions itself between these two layers.
No stationary phase, mobile phase, or detector is used in this type of extraction.
