Concept:Water and kerosene are immiscible liquids, meaning they do not mix and instead form separate layers.
A separating funnel is the correct apparatus for separating such layers.
Explanation:Water (
H2O) and kerosene have different densities.
Kerosene is less dense than water, so it floats completely on top of the water.
The mixture is poured into a separating funnel and left undisturbed until two distinct layers appear.
The stopcock at the bottom of the funnel is opened to drain the lower water layer first.
When all the water has drained out, the stopcock is closed and the kerosene layer is collected separately.
A filter funnel is used to remove insoluble solids from a liquid, not to separate two immiscible liquids.
A condenser is used in distillation to cool vapours, separating miscible liquids with different boiling points.
An evaporating dish is used to evaporate a liquid and leave behind dissolved solids.
Thus, the separating funnel best fits the separation of water and kerosene.
Answer:A. separating funnel.
