Sedimantation and decantation method are used to separate a mixture containing an insoluble solid in a liquid. In this method, the mixture is allowed to stand undisturbed for sometime. The insoluble solid substance settles down and a clear liquid is left standing. This clear liquid is called as supernatant liquid. The solid substance that settles down is called sediment. This entire process is known as sedimentation.
The clear water (supernatant liquid) is then poured out carefully into another beaker, leaving the sediments undisturbed. This process is known as decantation.

Supernatant Liquid:
The clear liquid left behind in the beaker after settling down of the sediments is called the supernatant liquid. This liquid is the top layer in a mixture of solid particles and liquid. Here's a detailed explanation:
Definition:
- The supernatant liquid refers to the clear liquid that remains on top of a solid substance after the solid has settled at the bottom of the container.
Formation:
- When a mixture of solid particles and liquid is left undisturbed, the solid particles settle at the bottom due to gravity.
- The clear liquid that remains above the settled solid is the supernatant liquid.
Characteristics:
- The supernatant liquid is usually clear and free of visible solid particles.
- It may have a different density or composition compared to the settled solid.
Importance:
- The supernatant liquid can be separated from the solid particles by carefully pouring or decanting it off.
- It can be further processed or analyzed for various purposes, depending on the nature of the mixture.
In conclusion, the supernatant liquid is the clear liquid that appears on top of settled sediments in a mixture. It plays a crucial role in the separation and analysis of mixtures containing solid particles and liquid components.
