Decantation for Class 6 is the process of carefully pouring the clear liquid from a mixture without disturbing the settled solid at the bottom. It is used after sedimentation , when heavier particles have already settled down.

Simple meaning

In easy words, if mud or sand settles at the bottom of water, you can gently pour the clean water into another container. The muddy part stays behind.

Example

A common example is a mixture of sand and water. First, the sand settles at the bottom, and then the top clear water is poured off.

Key point

Decantation does not use a filter paper. It only works when the solid particles have already settled or when the liquids do not mix well.

One-line definition

Decantation = pouring out the clear upper liquid without disturbing the sediment.
