What else can I help you with?
Why is it important that the sample spots are not below the solvent level when the filter paper is first placed in the developing chamber?
By placing the spot above the level of the solvent in the beaker, you slow the flow of solvent which results in improved separation of the components in the spot. If you placed it below the level of the solvent in the beaker, the solvent would just flow at a much faster rate and instead of separating the components in the spot, they would simply be washed away.
Why is the mixture placed above the level of the solvent in chromatography?
Placing the mixture above the solvent level in chromatography allows the solvent to travel up the stationary phase through capillary action, carrying the components of the mixture at different rates based on their interactions with the stationary phase. This separation process helps to distinguish and isolate the different components of the mixture.
Where did Arctic Circle placed above or down?
above
Which solution will have more gas dissolved in it?
The solubility of a gas in a solvent is directly proportional to the partial pressure of that gas above the solvent.
What would happen if you submerge the chromatography paper above the pencil line?
Submerging the chromatography paper above the pencil line would cause the solvent to rise above the line, potentially leading to the ink or pigment above the line to dissolve and be carried upwards with the solvent. This can result in the separation of different components within the ink or pigment.
Why must pencil line be drawn above the level of solvent?
Drawing a pencil line above the level of the solvent ensures that the compound being separated does not dissolve directly in the solvent, preventing interference with the separation process. This helps maintain a distinct separation between the solvent front and the compounds being separated, leading to more accurate results during chromatography.
Where is a Combat Action Tourniquet placed on a injury?
It's placed above the injury site
What is the difference between grave and tomb?
A tomb is a structure that typically is above ground in which the casket is placed. A grave is a hole in the ground in which the casket is placed. A tomb stone is a structure placed above a grave to mark the location of the grave.
WHAT TYPE OF SECURITY IS ( PART OF YOUR RESPONSIBILITY) AND PLACED ABOVE ALL ELSE?
Information security is part of your responsibility and placed above all else.
What would happen if the solvent is above the level of initial sample spots?
If the solvent is above the level of the initial sample spots in a chromatography experiment, it can lead to the sample being dissolved or dispersed throughout the solvent, causing smudging of the spots and inaccurate separation of components. This can result in poor resolution and difficulty in analyzing the components present in the sample.
Where is the bowie-dick test pack placed?
Best placed 50 - 100mm above the drain of the steriliser.
Where is a tourniquet placed on injury?
It is placed 2 to 4 inches above the wound.
