What is the primary purpose of the 3 Step Extraction method?

The primary purpose of the 3 Step Extraction method is to separate compounds based on their solubility. This method typically involves partitioning a mixture into different phases where solute substances distribute themselves according to their solubility properties in various solvents. As a result, it effectively isolates specific components from complex mixtures by taking advantage of differing solubility and polarity characteristics, allowing for a targeted extraction of desired compounds.

In the context of the other provided options, they relate to different analytical and chemical processes. Analyzing the chemical structure of a specimen requires different techniques such as spectroscopy, which is not within the scope of the 3 Step Extraction method. Reacting a specimen to produce color changes relates more to specific chemical tests or qualitative analysis rather than the extraction process. Enhancing the purity of a chemical compound is more aligned with purification processes rather than extraction specifically. The focus of the 3 Step Extraction method is fundamentally on separating rather than analyzing or enhancing purity.
