In chromatography, spots move due to the differential partitioning of compounds between a stationary phase and a mobile phase. As the mobile phase (usually a solvent) travels through or along the stationary phase (like a column or paper), it carries the different components of the mixture at varying rates based on their solubility and affinity for the phases. Compounds that are more soluble in the mobile phase will move faster, while those that interact more strongly with the stationary phase will move more slowly, resulting in separation of the spots.

What would it mean if a spot didn't move chromatography?
If a spot didn't move in chromatography, it typically indicates that the substance is not soluble in the mobile phase or has a strong affinity for the stationary phase, preventing it from migrating. This can suggest that the compound is either highly polar or has a high molecular weight compared to others in the mixture. Additionally, it may signify that the conditions of the chromatography (e.g., solvent composition) are not suitable for that particular substance. Overall, it implies that the interaction between the compound and the chromatographic materials is significant enough to retain the compound at its original position.
What does it mean if the spot is in the baseline in chromatography?
In chromatography, if a spot is located at the baseline, it typically indicates that the substance being analyzed did not move with the mobile phase during the separation process. This can occur if the compound has a very strong affinity for the stationary phase or if it is not soluble in the mobile phase. As a result, the substance may not be effectively separated from other components, leading to poor resolution in the chromatogram.
What are the factors that affect leaf chromatography?
Factors that affect leaf chromatography include the polarity of the solvent used, the size and shape of the molecules being separated, the pH of the solvent, and the temperature at which the chromatography is performed. These factors can impact the rate at which the molecules move through the chromatography medium and the resolution of the separation.
What is the name of the method used to separate dyes?
Chromatography is the method used to separate dyes by allowing the components to move at different rates through a medium, such as paper or a column, based on their affinity for the medium and solvent. This technique separates the different dyes based on their molecular interactions with the moving phase.
What is The appearance of chromatograms in paper chromatography?
The chromatogram in paper chromatography is just the paper itself. You can look at the paper and see the dots that have risen due to the solvent. The appearance is just simply a piece of paper with dots that have risen from the baseline to a certain spot on the paper. see related link below for more info

How do you calculate Rf in chromatography?
In chromatography, Rf is the distance the solute travels divided by the distance the mobile phase travels. For example, in thin layer chromatography, if the spot travels 7 cm, and the mobile phase travels 15 cm, the Rf value for that spot will be 7/15 = 0.47

How did Jew's move to there hiding spot?
First, the question should read:How did Jews move to their hiding spot?Assuming the question is meant seriously, it is unanswerable.• Jews move the same way anyone else does.• Which Jews, where, when, and what sort of hiding spot?• Permanently move to a permanent hiding spot, or temporarily move to a temporary hiding spot?

What if your elfontheshelf does not move?
if the elfontheshelf does not move its because that his or her favorite spot
How do you move on Moshi Monsters?
Click on the spot you want your Moshi Monster to move to and you will hear a whistle and your Moshi Monster will walk to the spot you clicked on. Use the arrows to move the scene from side to side to help choose a new spot for your Moshi Monster to move to.
What is chromatography paper called?
Chromatography paper is also called filter paper because it is commonly used to separate mixtures of substances based on their different polarities as they move through the paper.
What is the stationary phase for paper chromatography Material?
The stationary phase for paper chromatography is the material that stays fixed in place on the paper, allowing the mobile phase (solvent) to move through it and separate the components of a mixture.
Why does carotene travel farthest in chromatography of leaf pigments?
Carotene travels the farthest in chromatography of leaf pigments because it is the least soluble in the chromatography solvent. This means it interacts less with the solvent and more with the chromatography paper, allowing it to move further up the paper before the solvent front stops it.
