Question

Given below are two statements:

Statement I: A mixture of $C_{12}H_{22}O_{11}$ (sugar) and NaCl can be separated by dissolving sugar in alcohol, due to differential solubility

Statement II : Rose essence from rose petals is separated by steam distillation due to its high volatility and insolubility in $H_{2}O$.

In the light of the above statements, choose the correct answer from the options given below :

Options

A.Both Statement I and Statement II are true
B.Both Statement I and Statement II are false
C.Statement I is true Statement II is false
D.Statement I is false Statement II is true

Solution

Sol. [Key Concept: Sugar dissolves in alcohol while NaCl does not, so differential solubility separates them (Statement I true); rose essence is steam-volatile and water-insoluble, so steam distillation works (Statement II true).]

Sugar is soluble in alcohol not NaCl

So they are separated by solvent extraction (or differential extraction)

Rose essence oil is steam volatile so it is separated by steam distillation.
