The property of solvent determines the rate of migration of solute i.e., if the solvent is nonpolar, nonpolar molecules will move faster and if the solvent is polar, than polar molecules will move faster during separation.

A hypothesis for paper chromatography?

A hypothesis for paper chromatography depends on what you are making the hypothesis on. A hypothesis for the speed of chromatography could be that you think the speed of the process can be changed depending on the type of paper, or whatever the stationary phase is, and the type of solvent being used.


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 paper chromatography?

Paper chromatography is a laboratory technique used to separate and analyze mixtures of substances. It involves applying a sample to a strip of paper, which is then placed in a solvent and allowed to separate into its individual components based on their different affinities to the paper and the solvent. The separated components can be visualized as distinct bands on the paper strip.


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.


Why the descending method of chromatography is faster than the other method?

Descending chromatography is faster because gravity aids in pulling the solvent down through the stationary phase, allowing for quicker elution of compounds. In this method, the analytes travel with the solvent flow, resulting in faster separation compared to ascending chromatography where the solvent has to move against gravity.

Why one pigment moves faster than the other in paper chromatpgraphy?

The speed at which pigment molecules move during paper chromatography is determined by their size, shape, and polarity. Smaller, less polar molecules will typically move faster than larger, more polar molecules because they can more easily pass through the pores of the paper. Additionally, the interactions between the pigment molecules and the solvent used in the chromatography process will also affect their speed of movement.

What forces cause the eluding solvent to move along the chromatography paper?

The solvent moves along the chromatography paper due to capillary action, which is the result of the attractive forces between the solvent molecules and the paper. The solvent travels up the paper, carrying the components of the mixture with it as it moves through the stationary phase.

Why does different colour dyes move different speeds up charmatograhy paper?

What is charmatograhy paper? Just kidding! I assume you mean chromatography paper. Well, the answer to your question lies in the solubility of the different colour dyes. The more soluble the dye the faster it will travel across the paper. Also, some substances react better with the paper but I'm not sure that is the right answer.


How water acts as stationary phase in paper chromatography -exact role?

The hydroxyl groups in the chromatography paper lead to the hydrogen bonding of water, which in turn leads to a water layer that forms the stationary phaseSource:PSU CHEMTREK by Stephen Thompson. Hayden-McNeil, 2009, Chapter 18-7

What paper chromatography employs the attraction of the surface of a liquid to the surface of a solid?

Chromatography - The separation of components of a mixture based on how quickly different molecules dissolved in a mobile phase(liquid surface) solvent move along a solid phase(solid surface).


When energy is converted to molecules and they move faster does temperature increase or decrease?

As molecules move faster, they cause friction, which increases the temperature of the molecules.


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.


Which occurs when air is compressed A. Air Temp rises and air molecules move faster B. Air temp decreases C. Air temp decreases and air molecules move faster D. Air molecules move slower?

A. air temperature rises and air molecules move faster


Why some substances in chromatography will travel futher up the paper?

Substances travel further up the paper in chromatography due to differences in their affinity to the mobile phase (solvent) and the stationary phase (paper). Substances that have higher affinity for the solvent will move faster and farther up the paper, while those with higher affinity for the stationary phase will travel slower and remain closer to the origin.
