Supernatant solutions are liquids resulting from the separation of solids or precipitates from a mixture by centrifugation or settling. The supernatant is the clear liquid layer that sits on top of the settled particles and can be decanted or removed without disturbing the solid material. This technique is commonly used in laboratory settings to isolate and analyze compounds within a sample.
I think it's the bottom of the liquid when put through a centrifuge? I don't know either!
A solution formed on the surface from a mixture of solution after shaking the mixture or by some other means.

What is the color of supernatant liquid in decantation?
The color of the supernatant liquid in decantation can vary depending on the substances present in the mixture being separated. It could be clear, cloudy, or have a specific color if certain substances are dissolved in the liquid.
Why is it necessary to test for complete precipitation if a supernatant solution is going to be subsequently tested for ions?
It is necessary to test for complete precipitation to ensure that all ions have reacted and formed solid precipitates. If not all ions have reacted, some may remain in the supernatant solution and could give false results when testing for specific ions. Complete precipitation ensures accurate and reliable results when testing for individual ions in the supernatant solution.
What is the clear liquid above the sediment called?
The clear liquid above the sediment is called the supernatant. This liquid is often decanted or separated from the sediment in processes like centrifugation or settling.
What do you call the liquid obtained from decantation?
The liquid obtained from decantation is typically called the supernatant. It is the clear liquid that is poured off after the sediment has settled to the bottom of a container.
What solutions in which water is the solvent are called?
Solutions in which water is the solvent are called aqueous solutions.
What does the term supernatant refer to scientifically?
The term supernatant scientifically refers to lying above a precipitate or sediment. Supernatant scientifically also refers to floating on the surface of a liquid.
Supernatant and pellet?
Supernatant is the clear fluid above a precipitate or sediment. Pellet is a small rounded object, ball, or spherical body.
What is the solution that remains after a precipitate has formed?
Supernatant.
What is the color of supernatant liquid in decantation?
The color of the supernatant liquid in decantation can vary depending on the substances present in the mixture being separated. It could be clear, cloudy, or have a specific color if certain substances are dissolved in the liquid.
What is the use of resuspension of supernatant in fresh medium?
LB medium
When centrifuging a mixture the lighter material in the solution on top is called?
the supernatant
What is the difference between supernatant and filtrate?
supernatant - liquid above and solid in the bottom, the supernatant is the liquid above that is going to be poured off (to separate the solid and the liquid) filtrate - it is also the liquid part but the solid and liquid is separated differently, for example coffee the filter paper holds on to residue (solid) and the liquid part (filtrate) passes I think that is the difference.

The clear liquid above the sediment is called the supernatant. This liquid is often decanted or separated from the sediment in processes like centrifugation or settling.
Why did DNA in Hershey-Chase experiments end up in the supernatant?
In the Hershey-Chase experiments, DNA ended up in the supernatant because it is a large molecule that remained inside the bacterial cells, while the protein coat of the phage (which was labeled with radioactive sulfur) was stripped off and left outside the cell. This separation allowed researchers to conclude that DNA is the genetic material responsible for viral replication.
The liquid form in decantation called?
Decantation is the process of separating mixtures by removing the liquid and leaving behind the sediment. The liquid portion is called the decant.
Why is best to read test tubes as soon as supernatant is discernible in laboratory experiments?
To prevent it from mixing up again
