How is the retention factor measured in paper chromotography is related to pigmnet color in leaves?
The retention factor (Rf value) in paper chromatography is calculated as the distance the pigment traveled divided by the distance the solvent front traveled. The Rf value is unique for each pigment and helps identify and compare different pigments based on their mobility during chromatography. Pigments with higher Rf values move further up the paper, showing greater solubility, while pigments with lower Rf values stay closer to the solvent front.
In chromatography why do some colours not spread up the paper?
Some colors may not spread up the paper in chromatography because they may have a higher affinity for the stationary phase (paper) than the mobile phase (solvent). This means they are more likely to stick to the paper and not move as far as other colors.
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.
A component of solid liquid or gas what is that?
A component of a material refers to one of its distinct parts or elements that make up the substance. In a solid, the components are closely packed together in a fixed arrangement, in a liquid the components are still close together but can move past each other, and in a gas the components are far apart and move freely.
Are the particles of gas are packed tightly together?
No, they are not packed tightly together. The particles in solids are. In gas, they move in random motion and are the furthest apart, compared to solids and liquids. Hope this helps :)
How does chromotograhy work using particles?
Chromatography is a way of separating solutions. In schools dyes are usually used to illustrate this. Most dyes are actually solutions of different coloured chemicals. The colours are the solute particles. They are attracted by the solvent particles and the chromotography paper. Each solute is attracted by a different amount. When the colour is separated by chromotography the solutes which are held strongest by the solvent travel the furthest whereas the solutes that are held the strongest by the paper travel the least.
What happens in paper chromatography in inorganic ions?
In paper chromatography, inorganic ions can be separated based on their different affinities to the paper and mobile phase. As the mobile phase moves through the paper, ions with stronger affinities to the paper will move more slowly, causing them to separate from ions with weaker affinities. This differential migration will result in the separation of inorganic ions on the paper chromatogram.
Which phase of a substance are the particles furthest apart?
The gas phase is when particles are furthest apart because they have enough kinetic energy to overcome intermolecular forces and move freely in all directions.
Which one's bigger 0.7 or 0.07?
0.7 > 0.07. When comparing values always start from the digit furthest to the left. If these are equal move to the next furthest and so on.
How do you move a brick with paper?
you have to help me Mr. Nosiglia !!!!!!! I can't find how you move a brick with paper.........
How do you Bleed the brakes of a 1987 Dodge Dakota?
from the furthest caliper from the master cylinder. Start with that one and move closer.
Can the vibration of voice move somthing?
yes it can move a piece of paper ;]
Why wait 75 minutes for paper chromatography?
Waiting for 75 minutes in paper chromatography allows the solvent to travel up the paper, separating the different components of the mixture based on their solubility. This extended time period ensures that the components have enough time to migrate a sufficient distance for meaningful separation and analysis.
Why does waxed paper paper offers the least resistance to move on a ramp?
Because the waxed paper have less friction on it:)
What is it when the words move on paper?
When words move on paper, it could be due to an optical illusion called the "pulfrich effect" where the brain perceives movement when viewing contrasting colors or shades. It could also be a result of the paper or surface not being completely flat, causing the words to appear to move when the paper is moved.

Separation technique that identifies parts if a mixture based on how fast different compounds move across a material?
The separation technique you are referring to is called chromatography. In chromatography, different compounds in a mixture are separated based on their different rates of movement across a material (such as paper or a column filled with beads) due to differences in their affinity for the material and the solvent used. This process allows for the identification and analysis of individual components in a mixture.
