Solution
Separating the components of a mixture containing two immiscible liquids:
A suitable method for separating a mixture containing kerosene oil and water is by using a separating funnel.
Immiscible liquids: A mixture of two or more liquids that do not mix with each other and are present in the form of separate layers instead of one. Example: kerosene oil in water, vegetable oil in water.
Separating funnel: It is an apparatus in which two immiscible liquids can be separated with the help of a stopcock fitted on the stem of the funnel.
The principle involved in the separation of mixture:-
Two immiscible liquids have different densities due to which they are present in the form of two different layers which can be separated by a separating funnel.
The process of separation is as follows:
Take the mixture of two immiscible liquids and pour it in the separating funnel placed on a tripod stand.
Place an empty beaker below the stem of the separating funnel to collect the liquid.
The component of the mixture which has higher density will form the lower layer and the one with lesser density will float and form the upper layer.
These two separate layers are clearly visible.
Carefully open the stopcock of the funnel to allow the component in the lower layer to pass through.
Close the stopcock as the component in the lower layer approaches near the stopcock to avoid the intermixing of two components.
Thus, one component is separated and obtained in the beaker and other remains in the separating funnel which can eventually be transferred to another beaker.
