easy · MCQ · Q-213C67

A student wants to separate a mixture of two miscible liquids, acetone and water, whose boiling points differ by more than 25∘C25^\circ\text{C}. Which standard laboratory technique should be used?

  1. A.Simple distillationCorrect answer
  2. B.Fractional distillation
  3. C.Centrifugation
  4. D.Sublimation

Solution

Simple distillation is used for the separation of components of a mixture containing two miscible liquids that boil without decomposition and have a difference in their boiling points of more than 25∘C25^\circ\text{C} (acetone boils at around 56∘C56^\circ\text{C} and water at 100∘C100^\circ\text{C}).
