To separate oil from water, you would use decantation. Since oil floats on top of water due to its lower density, you can carefully pour the oil off the surface, leaving the water behind. This method works well for immiscible liquids.
In the chapter Materials Around Us, you have studied that oil does not mix with water and forms a separate layer when left undisturbed for some time. Which method of separation would you use to separate oil and water?

To separate oil from water, the most effective method is decantation. When oil and water are left undisturbed, oil forms a distinct layer on top of the water because of its lower density. By gently pouring off the oil layer from the top, you can separate it from the water below. This method is ideal for immiscible liquids that do not mix and naturally form separate layers. Decantation leverages the difference in density to achieve the separation efficiently and effectively.
