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.

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 the level ofthe solvent not reach the pencil line where the spots are?

If the solvent level reaches the pencil line where the spots are, it can dissolve the compounds in the mixture, causing them to spread out and overlap. This can lead to inaccurate results and difficulties in analyzing the separated components on the chromatogram. It's important to maintain the separation of the compounds on the chromatography plate for clear identification.


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.


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.


Why is it important that the level of the elution solvent not drop below the top of the absorbent?

If the level of the elution solvent drops below the top of the absorbent, it can cause the sample to dry out prematurely, leading to incomplete elution and loss of analyte. This can result in inaccurate or inconsistent results in chromatography. Maintaining the solvent level above the absorbent ensures proper elution and retention of the analyte through the stationary phase.

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 must the level of the solvent not reach the pencil line where the spots are?

Allowing the solvent to reach the pencil line could oversaturate the spot, leading to uneven separation and inaccurate results. It may cause the compounds in the spot to spread out too much or merge with neighboring spots, making it difficult to accurately identify and analyze the components.


What are A series of light brown lines drawn at intervals of 50 feet to designate their respective heights above sea level called?

Contour lines are a series of light brown lines drawn at intervals of 50 feet to designate their respective heights above sea level. They help to show the elevation and shape of the land on a topographic map.


How do you pass chapter 3 level 8 on save the pencil?

Hello guys! I was wondering is there a way to beat chapter 3 level 8 in Save The Pencil? I like Save The Pencil and I've been playing it for a while, but now I can't figure out how to beat Save The Pencil chapter 3 level 8? Any ideas on how to finish chapter 3 level 8 in Save The Pencil would be greatly appreicated!


What would happen if the Spot of origin is lowered into the solvent in chromatography?

If the original spots were below the level of developing solvent then the components of the spotted sample would dissolve into the solvent and no spots would be seen upon analysis because all of the sample is dissolved in the developing solvent. hope this helps. good luck in o. chem!
