Solvent extraction method is particularly useful technique for separation when the product to be separated is:
Correct answer: C. volatile or thermally unstable
- A. non-volatile or thermally unstable
- B. non-volatile or thermally stable
- C. volatile or thermally unstable
- D. volatile or thermally stable
Explanation
Solvent extraction is particularly useful when dealing with volatile or thermally unstable products because it allows for the separation of components without subjecting them to high temperatures. This method relies on the differential solubility of substances in a chosen solvent. For volatile or thermally unstable compounds, traditional separation methods like distillation can be impractical since they involve heating. Solvent extraction operates at lower temperatures, reducing the risk of degrading or losing the desired product. It's especially effective for extracting delicate compounds from mixtures without compromising thei

About Experimental Techniques in Chemistry
Separation methods are selected according to differences in solubility, particle size, volatility and sublimation behaviour. Filtration and crystallisation separate insoluble or dissolved solids, sublimation isolates suitable volatile solids, distillation separates liquids by boiling point, and solvent extraction transfers a substance between immiscible solvents.
