Question

The solvent used for extraction must have ..... inflammability and ..... viscosity​

Answer 1

Answer:

The solvent should have low solubility in the feed solution, otherwise the separation is not "clean". If distillation is to be used, the solvent should form no azeotrope with the extracted solute and mixtures should show high relative volatility.

Answer 2

Answer:

The solvent used for extraction must have zero inflammability and low viscosity​

Explanation:

Characteristics of a good solvent for extraction are:

• It must have good solubility of the target compound
• It should have Poor solubility of the impurities
• It should be Non toxic
• It should be Non-flammable
• It should have Low Viscosity
• It should be inexpensive and cost-effective
• The density of the solvent should be different from the target compound so that the compound can be removed easily.
