Why does alkyl halide layer switch from top layer to bottom layer at the point were water is used to extract the organic layer?
The alkyl halide layer switches from the top layer to the bottom layer during extraction with water because alkyl halides are less soluble in water compared to organic solvents. When water is added, the alkyl halide molecules preferentially partition into the water layer, causing them to move from the organic layer (usually on top) to the aqueous layer (usually at the bottom).
Which layer in a soil profile contains the most organic matter?
The O horizon contains the most organic matter. The O horizon overlies the A horizon which is known as the mineral horizon. O - organic A - mineral E - elluviation B - illuviation C - parent material R - bedrock This is the order in which you will see standard soil horizons.
What is the layer is above the permafrost?
The layer above permafrost is known as the active layer. It is the top layer of soil that thaws and refreezes seasonally in response to changes in temperature. This layer plays a crucial role in supporting vegetation growth and allows for water movement in the soil.
What is the top crust layer of earth called?
The top crust layer of the Earth is called the crust.
Why does the distillate collected from the steam distillation has aniline as the bottom layer and after saturation with sodium chloride the aniline becomes the top layer?
In steam distillation, aniline, which is less dense than water, typically collects as the bottom layer due to its higher boiling point and lower volatility compared to water. However, when sodium chloride is added to the mixture, it increases the ionic strength and alters the solubility of the components. This change can lead to a phase separation where the aniline becomes less soluble in the aqueous layer, causing it to rise and form the top layer instead. The addition of salt effectively "salts out" the aniline, making it less dense than the saline water layer.
When you are extracting an aqueous solution with an organic solvent you are uncertain of which layer in the separatory funnel is aqueoushow would you quickly sort out the issue?
Add a drop of water and see if it mixes with the top layer or if it remains as a droplet within the top layer. If it mixes homogeneously, then the top is aqueous. If it forms a droplet, then the top is organic.

Do you observe the halide test in the upper layer or lower layer?
upper layer
Is it possible to have an inversion of the two phases during the extraction step of DNA with the organic phase located on top of the aqueous phase?
is it possible to have an inversion of the two phases during extraction step of DNA, with the organic phase located on the top the aqueous phase
What do scientist call the top layer of a soil profile?
Scientists call the top layer of a soil profile the "O horizon" or "organic horizon." This layer consists of organic material such as leaves, twigs, and other plant debris that are in the process of decomposing.
Which layer in the diagram below contains the most organic material?
The layer that contains the most organic material in the diagram is the top layer, known as the O horizon or organic horizon. This layer is made up of decomposing organic matter such as leaf litter and other plant debris.
What is a clevenger apparatus?
Clevenger apparatus is used to determine the volatile oil content in a given sample. The oil layer settles on top of the aqueous layer.
What are soil levels made up of and how deep are they?
there is the organic layer which is the top most layer and its about 8cm deep
What is the name the top layer of soil?
The top layer of soil is called topsoil. It is rich in nutrients and organic matter, making it ideal for plant growth.
Why is the top layer of the ocean the warmest-?
The top layer of the ocean is the warmest because it is always in contact with the sun.
What is the top layer of dirt called?
The top layer of dirt is called topsoil. It is the uppermost layer of soil and contains the highest concentration of organic matter and nutrients needed for plant growth.
What is the meaning of the layer soil?
it is the top layer of the earth's surface consisting of rock and mineral particles mixed with organic matter.
