Question 62

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 :

A mixture of sucrose ((C_{12}H_{22}O_{11})) and sodium chloride can be separated by exploiting their difference in solubility. Sucrose is soluble in alcohol, whereas sodium chloride is practically insoluble. On adding alcohol, sucrose dissolves while sodium chloride remains undissolved and can be separated by filtration.

Therefore, Statement I is true.

Steam distillation is used for substances that are volatile in steam and immiscible with water. Rose essence is an essential oil that is steam-volatile and insoluble in water, allowing it to be separated from rose petals by steam distillation without decomposition.

Therefore, Statement II is also true.

Hence, both Statement I and Statement II are true.
