Learning Objective
I can evaluate different separation techniques for purifying a specific chemical substance.
- 1
In extraction, physical properties like solubility or chemical properties like reactivity can be used to separate substances.
- 2
A separatory funnel is used to separate immiscible liquids into layers based on density, allowing for the isolation of different components.
- 3
To recover the original compounds after extraction, salts can be converted back by adding a strong acid or strong base to precipitate the desired product.
