Distinguish between miscible and immiscible liquids. Name the techniques used to separate these liquids.

(N/A) Miscible liquids: These liquids mix with each other completely to form a single phase.
Immiscible liquids: These liquids do not mix with each other and form separate layers.
Techniques for separation:
$1$. For miscible liquids: Distillation or fractional distillation is used based on the difference in their boiling points.
$2$. For immiscible liquids: $A$ separating funnel is used to separate them based on the difference in their densities.
