Question

what is meant by sedimentation and decantation ? what are they used for?​

Answer 1

Explanation:

Overview. 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.

Answer 2

$\huge\mathfrak{\underline{\underline{\red{sedimentation}}}}$

Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism.

$\huge\mathfrak{\underline{\underline{\red{decantion}}}}$

Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. ... An incomplete separation is witnessed during the separation of two immiscible liquids.
