What would happen if you allowed the paper to sit in the solvent for 10 minutes after the solvent reached the top?
If the paper is allowed to sit in the solvent for 10 minutes after the solvent has reached the top, it may lead to excessive diffusion of the solutes, potentially causing the separation of components on the paper to become less distinct. The prolonged exposure can result in smearing or running of the spots, making it harder to interpret the results accurately. Additionally, the paper may become oversaturated, which could affect the overall chromatographic resolution.

What would happen if the student did not stop the chromatograph before the solvent reached?
If the student did not stop the chromatograph before the solvent reached the end of the chromatographic medium, the separation of the components would likely be compromised. The substances would continue to travel with the solvent front, potentially leading to overlapping spots and making it difficult to accurately identify and quantify the separated compounds. Additionally, it could result in a loss of resolution, making the analysis less reliable. Ultimately, the effectiveness of the chromatographic technique would be diminished.
What 2 things must happen for a solute to dissolve in a solvent?
The bonds between ions or molecules of the solvate must be broken. The solvent must be in a sufficient amount and an adequate temperature.
What happen when solvent is equal to solute?
When the amount of solute is equal to the amount of solvent, the solution becomes saturated. This means that no more solute can dissolve in the solvent at that temperature. Any additional solute added will remain as undissolved solid at the bottom of the container.
What needs to happen for a solute to dissolve in a particular solvent?
For a solute to dissolve in a particular solvent, the intermolecular forces between the solute and solvent particles must be stronger than the forces holding the solute particles together. This allows the solute molecules to separate and become surrounded by solvent molecules, forming a homogenous mixture. Temperature, pressure, and the nature of the solute-solvent interactions also play a role in determining solubility.
What would happen to the Rf value if a chromatography strip was twice as long and half as long?
No, because the distance a compound moved in relation to the solvent front is relative. The higher up the solvent front the greater the distance travelled by the compound. Remembering that Rf is always <1.
What will happen to the solute when dissolved in solvent?
the particles of the solute would be spread to the solvent particles.
What happen when salt is dissolved in water?
it turns to a solvent
What would happen if is not soluble in the solvent?
If a solute is not soluble in a particular solvent, it will not dissolve and will remain as a separate phase in the solvent. This can result in the formation of a suspension or precipitate, depending on the nature of the solute and solvent.
What will happen to the soulubility of salt if you heat the solvent?
The solubility will increase.
When more solvent is added what will happen to concentrated solutition?
It becomes diluted.
What would happen to soldiers as they reached WW1?
they would die
What will happen when a cell is placed in a medium with solvent-solute content equal to that of the cell?
It will then be in an isotonic/isosmotic environment, and nothing will happen to the cell.
What 2 things must happen for a solute to dissolve in a solvent?
The bonds between ions or molecules of the solvate must be broken. The solvent must be in a sufficient amount and an adequate temperature.
What happens to a solute?
It gets dissolved in something else.
What happen to De Soto when he reached Florida?
He got laid and caught a STD.
What groups allowed the Holocaust to happen?
The Nazi Party of Germany allowed the Holocaust to happen so the German people would be unified against the Jewish people.
What is going happen when shopping carts are allowed in escalators?
if shopping carts are allowed in escalators an escalator accident will happen you know that escalator accidents are hard to survive.
