Correct option is D

The correct answer is (d) Immiscible liquids.
· A separating funnel is used to separate a mixture of immiscible liquids, which are liquids that do not mix together and form separate layers.
· When the mixture is placed in the funnel, the denser liquid settles at the bottom and can be drained out first, while the less dense liquid stays on top.
· This method is commonly used in laboratories to separate liquids like oil and water, where one liquid is less dense than the other and they do not form a homogeneous mixture.
Additional Knowledge:
· Miscible liquids: These liquids mix uniformly, and a separating funnel is not suitable for separating them. Instead, techniques like distillation are used.
· Salt and camphor: These substances would be separated using sublimation, not a separating funnel.
· Dye in a black ink: This would typically require separation by chromatography, not a separating funnel.
