Question

what is sedimentation and dicentation?​

Answer 1

Answer:

Sedimentation is defined as the separation process in which solids are separated from the liquid. All the solids settle down at the bottom of a beaker and on top, a clear layer of liquid is obtained. Decantation is defined as the separation process in which two immiscible liquids are separated.

Answer 2

$\to$Sedimentation and decantation methods are used for the separation of insoluble substances which are heavier than liquid. In the sedimentation process, heavier components of the mixture settle on the bottom, due to gravity. Decantation follows sedimentation.
