Difference between sedimentation and decantation
Sedimentation |
Decantation |
It is a process in which an sediment Is settled down at the bottom. |
The process of separation of two immiscible liquids by pouring one is called decantation. |
In these process one substance settle down at the bottom of flask and the upper substance can be separated by pouring. |
In these process two Liquids are immiscible which does not get mixed and form two layers. Which can be separated by removing upper layer. Or filtering lower layer. |
Sedimentation involves two phases – one Phase is solid and another is liquid phase. |
Decantation also involves two phases – it May be solid – liquid phase and another may be liquid – liquid phase. |
In the Sedimentation Insoluble impurity settled down as an sediment. And soluble substances remains with the liquid above. |
In the decantation lighter liquid is floating above the heavier liquid. |
Example for the Sedimentation Is –
Soil and water – The soluble part of soil dissolve with water after some time an sediment of soil deposited at the bottom of flask and water is over it. These water can be decanted or poured off. And the residue remains at the bottom thus we can separate the Two components. |
Example for the decantation is – oil and water –oil Being lighter and float over the water which can be poured down and separate the Oil from the water. |
