Question

A mixture of ${\mathrm{SO}}_2$, ${\mathrm{H}}_2$ and ${\mathrm{Cl}}_2$ can be separated by________ followed by _________.

• A. diffusion
• B. fractional evaporation

Answer 1

Diffusion $\Rightarrow$ The diffusion can be explained as the process of movement of a substance mixing of a substance from the region of higher concentration to the lower concentration as it can be spread uniformly.

For Eg.$\Rightarrow$ The spreading of perfume.

Fractional evaporation $\Rightarrow$ It is a process of separating of two or more miscible liquids at different temperatures.

For Eg. $\Rightarrow$ Paraffin wax.

A mixture of ${\mathrm{SO}}_2$,${\mathrm{H}}_2$ and ${\mathrm{Cl}}_2$ can be separated by diffusion followed by evaporation.
