What are separation technique plus physical property used for separation of water and cyclohexane
Accepted Answer
Separation Techniques and Physical Properties Used for Separation of Water and Cyclohexane
1. Distillation:
- Physical property: Difference in boiling points (100 °C for water, 80.7 °C for cyclohexane)
2. Liquid-Liquid Extraction:
- Physical property: Difference in solubility in an immiscible solvent (e.g., dichloromethane)
3. Centrifugation:
- Physical property: Difference in density (water is denser than cyclohexane)
4. Decantation:
- Physical property: Immiscibility and difference in density
5. Chromatography:
- Physical property: Different affinities for a stationary phase (e.g., silica gel, alumina)
Principle: These techniques utilize the differences in physical properties between water and cyclohexane to separate them. Distillation and extraction rely on differences in volatility and solubility, while centrifugation and decantation exploit differences in density and immiscibility. Chromatography involves the selective adsorption of components onto a solid surface.
