Supernatation is a term used in chemistry that refers to the process where a solid substance settles at the bottom of a liquid substance. There are several other terms that are commonly used to refer to this process. One such term is sedimentation, which is the process of settling of a solid substance that is heavier than the liquid it is suspended in. Another term is precipitation, which refers to the formation of a solid substance that separates from a liquid solution. Flocculation is yet another term used to describe the process of clumping of particles of a solid substance in a liquid solution. All these terms are synonyms of supernatation that are used in chemistry to describe similar phenomena.
