Answer 1

The correct answer is Distillation.

Key Points

Distillation
- It Separates a mixture of two miscible liquids (Miscible liquids are one that together when mixed, form a homogenous mixture whose composition is the same throughout.)
- A liquid mixture's components are vaporized, condensed, and then separated here.
- As the mixture is heated, the volatile component vaporizes first.
- The vapour is deposited in a liquid state after passing through a condenser.
- EXAMPLE - separation of gasoline from crude oil, formation of freshwater from salt-water.

Additional Information

Sublimation	Separating components of a mixture containing a non-sublimable impurity and a sublimable volatile solid.	Sublimation is the mechanism of a material transitioning from a solid state to a gaseous state without going through a liquid state. The material, that is solid, which is sublime, undergoes subtilization and hence the separation. EXAMPLE - When heated, ammonium chloride transforms from a solid to a gas, it is sublime. Hence getting separated.
Chromatography	Separation of solutes from the solvent or mixture.	This separation approach is founded on the fact that two substances can be dissolved in the same solvent but have different solubilities. The portion that is more soluble in the mixture rises faster and separates from the rest. EXAMPLE -Separating different components of the ink.
Crystallization	It involves the separation of solid-liquid separation technique, which involves the transfer of solute to the pure solid crystalline phase from the liquid solution.	Crystallization is an example of physical change. And it’s related to physical change as it doesn’t involve the formation of any new substance.
