What is meant by the terms decantation and filtration?
The larger and heavier solid particles settle down leaving the clear liquid above it. ... At the same time, during decantation, there is a chance of the particles mixing back in the liquid. The filtration technique can be used to overcome this as well. Thus, filtration is better than sedimentation and decantation.
Can you separate cooking oil from water by filtration?
No, it is hardly possible to filtrate one of the two fluids in an heterogeneous mixture. This can better be done by centifuging.
How is crystallization better than evaporation?
Crystallization is better than evaporation in mainly two ways, : 1. in evaporation, the solution needs to be at the boiling point of the solvent, the whole time. This may degrade the solute. 2. in crystallization, the crystals automatically throw away impurities to arrange themselves in a regular manner. Therefore, the degree of purity is higher than the solute left after evaporation.
How can you separate kerosene and water from sedimentation?
To separate kerosene and water from sedimentation, you can use a process called decantation. Allow the mixture to settle so that the sedimentation settles at the bottom. Carefully pour off the kerosene layer, leaving the water and sediment behind. You may need to use a separating funnel for better precision in separating the layers.
Why filtration process is better than sedimentation and decantation process?
Decantation and filtration both are used to separate parts of a mixture from one another. Decantation is the process of separating a liquid from a solid by gently pouring the liquid from the solid so as not to disturb the solid. Filtration is the process of separating a solid from a liquid by means of a porous substance (filter) which allows only the liquid to pass through. In AP Chemistry

How is centrifugation better than filtration?
Filtration is a general term most often characterized by size separation (trap larger objects while letting smaller objects through, by chemical bonding/breaking, or electrostatic attraction. Centrifugation works with specific gravities or densities of materials to separate them. Which is better depends on what materials are being separated, and at what volumes.

Why Suction filtration is better than gravity filtration?
Suction filtration is typically faster and more efficient than gravity filtration because it uses a vacuum to pull the liquid through the filter paper or membrane, resulting in quicker filtration. Additionally, suction filtration is often more effective at removing smaller particles due to the enhanced force applied to the filtration process.
How do you separate gasoline and water where gasoline forms the upper layer in the mixture?
Use a separatory funnel to pour the mixture into it and allow it to sit until the layers separate. Open the stopcock to drain off the lower water layer, leaving the gasoline in the upper layer. Repeat the process if necessary for better separation.

How could you remove pebbles from a mixture of pebbles and water?
Filtration will separate the pebbles and water ... Pour the mixture through a strainer (or better yet, an old burlap bag) and catch the water in a bucket. The pebbles will remain in the strainer or bag.
Would a longer fractioning column be more efficient in separating mixtures than a shorter one?
Yes, a longer fractioning column would generally be more efficient in separating mixtures than a shorter one. This is because a longer column allows for more separation stages and more interaction between the components of the mixture, resulting in better separation.
Would you be better buying a trash compactor than separating out the recyclables from your refuse?
You would be better off separating recyclables. No matter how much you smash garbage it is still there. Recycling keeps most garbage out of landfills and is good for the environment.
Why is crystallization better than evaporation for the separation of mixtures?
This affirmation is not generally valid.
