Advantages of multiple extraction

Answer 1

Advantages of multiple extraction

Explanation:

• When you extract, the residue will have the same concentration of material as the extract itself. If you extract again, the concentration will be lower, in the extract as well as in the residue.
• So with multiple extractions the amount of material left in the residue will be lower, ergo the extraction will be more complete.
• Extraction is a method used for the separation of organic compound from a mixture of compound. This technique selectively dissolves one or more compounds into an appropriate solvent. The solution of these dissolved compounds is referred to as the extract.
