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.
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!
What property water is most important for living organisms?
liquid
How the solution is form in the molecular level?
In a solution, the solute particles (e.g. sugar) are surrounded by solvent molecules (e.g. water) due to intermolecular forces. These solvent molecules form a hydration shell around each solute particle, pulling them apart and dispersing them throughout the solvent. This process occurs at a molecular level to create a homogenous mixture.
What compose a solution?
A solution is composed of a solute (the substance being dissolved) and a solvent (the substance doing the dissolving). These two components form a homogeneous mixture where the solute is evenly distributed in the solvent at a molecular level.

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 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.

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.
What is eco solvent printing?
Explore the market for entry-level eco-solvent outdoor printers and make a wise investment in your outdoor printing equipment.
Is it possible to increase a solvent's boiling point to more than 2500C?
The boiling point of beryllium is 2742 °C at sea level. If you can't move the solvent's boling point, you can always choose a different solvent.
Why would a substance dissolving in one solvent but not in another?
A substance may dissolve in one solvent but not in another due to differences in polarity, intermolecular forces, or chemical interactions between the solute and solvent molecules. The solute must be compatible with the solvent at a molecular level in order for dissolution to occur.
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.
