Decantation is a technique used in separating a less-dense substancefrom a dense one. In the process of decantation, the mixture is leftundisturbed. When the components are separated, the less dense substancecould be removed by scooping using a spoon or it can be removed by slowlypouring out the less-dense substance. Oil in water could be removed usingthe decantation technique. The fats that float in your sinigang could beremoved by decantation or scooping.Some of the mixtures that can be separated by decantation are thefollowing:A. oil in waterB. Gasoline in waterC. Sinigang with floating fatsD. Mud and water

Answer:You're absolutely right! Decantation is a simple and effective way to separate mixtures based on density. Here's a breakdown of why the examples you provided are suitable for decantation: A. Oil in water: Oil is less dense than water, so it floats on top. Decantation allows you to carefully pour off the water, leaving the oil behind. B. Gasoline in water: Gasoline is also less dense than water, so it will form a layer on top. Decantation can be used to separate them. C. Sinigang with floating fats: The fats in sinigang are less dense than the broth, causing them to float. You can remove these fats by carefully scooping them off or by carefully decanting the broth, leaving the fats behind. D. Mud and water: Mud particles are denser than water, but they will often settle to the bottom of the container. Decantation can be used to pour off the clear water, leaving the mud behind. Key Points about Decantation: - Density is key: The success of decantation relies on the difference in density between the substances. The less dense substance will always form a layer on top.- Time for settling: Sometimes, you need to let the mixture settle for a while to ensure the denser substance settles to the bottom.- Careful pouring: Slow and steady pouring is crucial to avoid disturbing the settled layers and mixing the substances again. Let me know if you have any other questions about separating mixtures!
