Decantation is a separation technique used to remove a liquid from a denser solid or another liquid by carefully pouring off the top layer. It works because the denser substance settles at the bottom, while the less dense one remains on top. This method is commonly used to separate oil from water or clear water from muddy mixtures.Let me know if you need more help! If this helps, feel free to mark it Brainliest
Decantation separates substances based on density differences. The less dense substance is poured off, leaving the denser substance behind.
