Explain differential extraction.
(N/A) Differential extraction is a technique used to separate an organic compound from an aqueous solution.
$1$. The process involves shaking the aqueous solution containing the organic compound with an organic solvent in which the compound is more soluble than in water.
$2$. The organic solvent and the aqueous solution must be immiscible,forming two distinct layers that can be separated using a separatory funnel.
$3$. After shaking,the layers are allowed to settle. The layer containing the organic compound is separated.
$4$. The organic solvent is then removed by distillation or evaporation to recover the pure organic compound.
$5$. If the compound is less soluble in the organic solvent,a large quantity of solvent is required. In such cases,continuous extraction is employed,where the same solvent is repeatedly used for extraction.
