Question

Difference between sedimentation
And decantation.

Answer 1

Decantation  refers  to  the  process  of  seperating  mixtures  by  removing  a  layer  of  liquid.
Sedimentation  refers  to  the  process  of  settling  down  of  heavy  solids in  a  mixture  of  an   insoluble  liquid   and    a  liquid  .

Answer 2

Decantation is followed by sedimentation.Decantation is the process by which sedimented liquid is seperated by pouring it in the other container very slowly without disturbing the setteled sediments at the bottom of the container. Sedimentation is the process of settling down of heavy insoluble impurities.
