Question

A mixture of ${\mathrm{SO}}_2$, ${\mathrm{H}}_2$_, and ${\mathrm{Cl}}_2$ can be separated by ______ followed by ______

Answer 1

Part 1:

• Diffusion: It is the process of separation of the mixture on basis of its density.
• Density: It is defined as a measurement of how tightly a material is packed.
• It depends upon the mass of the material. As the mass increases the density increases.
• ${\mathrm{SO}}_2$ (Sulfur dioxide) and ${\mathrm{H}}_2$ (Hydrogen) differ from each other in terms of density.

Therefore can be separated using diffusion.

Part 2:

• Fractional distillation: It is the process of separating a liquid mixture which is having a similar boiling point.
• These vaporization and condensation processes will occur several times.
• It is not a type of chemical reaction but a physical technique for the separation of a mixture of liquid.
• ${\mathrm{H}}_2$ (Hydrogen)and ${\mathrm{Cl}}_2$(Chlorine) can be separated using fractional distillation.

Hence, a mixture of SO₂, H_2, and Cl₂ can be separated by diffusion followed by fractional distillation
