what is decantation

Decantation is a separation method used to gently pour off a liquid from a mixture, leaving behind a solid sediment or a heavier liquid layer. It works because the components have different densities and have already been allowed to settle.

Quick Scoop

In simple terms, decantation means:

• Let the mixture stand still.
• The heavier part settles at the bottom.
• Carefully pour the clearer top liquid into another container.

Common Examples

• Separating sand or mud from water after it settles.
• Separating oil and water, which do not mix.
• Pouring wine carefully to leave sediment behind.

Key Point

Decantation is easy and useful, but it is not perfectly precise, so a little contamination can remain in the poured liquid.
