Extraction Extraction is the process of selectively removing a compound of interest from a mixture using a solvent. For an extraction to be successful the compound must be more soluble in the solvent than in the mixture. Additionally the solvent and mixture must be immiscible (not soluble in one another). Making tea is a good example of
