Decantation: Decantation is the process of separation of liquid from solid and other immiscible (non-mixing) liquids, by removing the liquid layer at the top from the layer of solid or liquid below.
Example: Separation of oil and water.
When we leave the mixture of oil and water, two separate layers are formed, with water at the bottom and oil, being lighter, at the top.
We can remove the oil layer from the top by pouring it into another vessel, which leaves us with the water layer at the bottom.
