Zorluk: OrtaSimple and Fractional Distillation

Match each distillation apparatus component or process listed on the left with its correct function or application on the right.

  • Fractionating columnProvides a large surface area for continuous condensation and re-vaporisation cycles.
  • Liebig condenserCools hot vapor to convert it back into a liquid state using circulating cold water.
  • Simple distillationSeparates a pure solvent from a solution or miscible liquids with widely different boiling points (>50∘C>50^\circ\text{C}).
  • Fractional distillationSeparates miscible liquids with close boiling points (<25∘C<25^\circ\text{C}) into individual components.

Cevap

Fractionating column matches with providing a large surface area for continuous condensation/vaporisation; Liebig condenser matches with cooling hot vapor using circulating cold water; Simple distillation matches with separating liquids with widely different boiling points; Fractional distillation matches with separating miscible liquids with close boiling points.
Each item is correctly matched based on standard laboratory separation techniques: the fractionating column increases efficiency for close boiling point mixtures by providing surface area, the Liebig condenser turns vapor to liquid distillate, simple distillation separates substances with large boiling point differences, and fractional distillation resolves mixtures of miscible liquids with close boiling points.

Adım Adım Çözüm

1
Identify the primary role of structural apparatus components
The fractionating column provides surface area for multiple equilibrium stages, while the Liebig condenser serves purely to condense vapor into liquid distillate.
Apparatus functions are based on physical design principles of distillation setups.
2
Differentiate between simple and fractional distillation based on boiling point criteria
Simple distillation is suitable for large boiling point differences (>50∘C>50^\circ\text{C}), whereas fractional distillation is required for close boiling points (<25∘C<25^\circ\text{C}).
Close boiling points require repeated vaporisation-condensation steps achieved only via a fractionating column.
