Smaller and less polar molecules generally move faster in paper chromatography because they interact less with the stationary phase (the paper) and can travel more easily through the solvent. Larger and more polar molecules tend to move more slowly as they have stronger interactions with the paper.

A hypothesis for paper chromatography?
A possible hypothesis for paper chromatography could be: Different molecules in the mixture will separate and move at different rates along the paper strip due to variations in their solubility and affinity for the stationary phase.
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.

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.
Why does different colour dyes move different speeds up charmatograhy paper?
Different color dyes move at different speeds on chromatography paper due to variations in their molecular size, shape, and polarity. These factors influence how strongly the dye molecules adhere to the paper and interact with the solvent, leading to differences in the rate at which they are carried along the paper by the solvent.
How water acts as stationary phase in paper chromatography -exact role?
In paper chromatography, water acts as the stationary phase by providing a medium for the sample to move through. The water molecules are absorbed on the paper and interact with the sample molecules, causing them to separate based on their affinity for the water molecules. This allows for the different components of the sample to migrate at different rates and be separated.

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.
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.
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
