The distance a pigment travels up the paper in paper chromatography is determined by its solubility in the solvent being used, its molecular size, and its attraction to the paper. Pigments that are more soluble and smaller in size tend to move further up the paper, while those with stronger interactions with the paper tend to stay closer to the origin.

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 happens when you shine a red light on a blue piece of paper?
The paper appears dark because red light is absorbed by the blue pigment, not reflected. The blue pigment absorbs red light and reflects blue light, which is why the paper appears blue under white light.
What are Two factors which determine the distance a substance travels up the paper?
The two factors that determine the distance a substance travels up the paper in paper chromatography are the solubility of the substance in the solvent and the affinity of the substance for the paper.
What are the two properties that determine the speed of the moving pigments?
The speed of moving pigments is determined by two properties: the viscosity of the fluid they are in and the size of the pigment particles. Higher viscosity and larger particle size typically result in slower pigment movement, while lower viscosity and smaller particle size lead to faster movement.
Is the seismograph a small needle moves across a graph paper by shaking when seismic waves hit The farther it moves the more powerful the seismic wave is this true or false?
True. A seismograph is a device that records the intensity and duration of seismic waves during an earthquake. When seismic waves hit, a small needle attached to a mass moves across a graph paper, creating a seismogram that shows the amplitude and frequency of the waves. The farther the needle moves, the more powerful the seismic wave is.
Which determines the speed with which a pigment moves up the chromatography paper?
Chromatography is a technique that separates molecules from each other on the basis of their solubility in particular solvents. As a nonpolar solvent moves up the chromatography paper, the pigment moves along iwth it. The more non-polar a pigment, the more soluble it is in a nonpolar solvent, and the faster and father it proceeds up the chromatography. Pg 94, laboratory 8.1, Inquiry into Life, Sylvia S. Mader, laboratory manual, 12th edition
Which pigment in chlorophyll moves the fastest?
Chlorophyll b typically moves faster than chlorophyll a during paper chromatography due to its higher polarity and increased ability to interact with the paper and solvent.
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.
What is factors that influences the movement of pigment on filter paper?
Factors that influence the movement of pigment on filter paper include the size, shape, and polarity of the pigment molecules, the type of solvent used to dissolve the pigment, and the absorption properties of the filter paper. Additionally, temperature and humidity can also affect the rate of pigment movement.

What is coloured paper made of?
Dye/Pigment is added during the papermaking process.
Why does red litmus paper reacts in acid and bases?
Red litmus paper contains a pigment that changes color in response to changes in pH. In acidic conditions, the pigment in red litmus paper turns red because the hydronium ions in the acid react with the pigment. In basic conditions, the pigment does not change color because the hydroxide ions in the base do not react with the pigment.
What will be the color of a sheet of paper containing red pigment when yellow light shines on it?
The red pigment in the paper will absorb all colors except red, which will be reflected. When yellow light shines on the paper, which contains red pigment, the red pigment will absorb the other colors in the yellow light spectrum but reflect the red light. So, the paper will appear red under yellow light.
What will be the color of a paper containing red pigment when yellow light shine on it?
The paper containing red pigment will appear red when yellow light shines on it. This is because red pigment absorbs most colors of light except red, which it reflects. So, the red pigment on the paper will reflect red light and appear red when illuminated by yellow light.
What factors that influence the movement of pigment on the filter paper?
temperature
What do the Rf values indicate about the relative solubility of the pigment in the the solvent?
The Rf value indicates the ratio of the distance a pigment travels compared to the distance the solvent travels on a chromatography plate. The higher the Rf value, the more soluble the pigment is in the solvent used for the chromatography.
What Determines the day for a planet?
