Current Question (ID: 10954)

Question:

$\text{A mixture of calcium sulphate and camphor can be separated by-}$

Options:

1. $\text{Filtration}$
2. $\text{Evaporation}$
3. $\text{Sublimation}$ (Correct)
4. $\text{Chromatography}$

Solution:

$\text{Hint: The process of sublimation is used to separate sublimating substances from non-sublimating compounds}$ $\text{In this process, the sublimable compound changes from solid to vapour state without passing through the liquid state. Camphor is a sublimable compound and calcium sulphate is a non-sublimable solid. Hence, on heating, camphor will sublime while calcium sulphate will be left behind.}$
