What is solvent action?
Solvent action refers to the process where a solvent dissolves a solute to form a solution. This occurs when intermolecular forces between the solvent and solute molecules are stronger than the forces holding the solute together. Characteristics like polarity and solubility play a key role in determining the effectiveness of solvent action.
What is the purpose of the solvent in chromatography?
The solvent in chromatography helps to carry the sample through the stationary phase (e.g., paper, silica gel) by allowing the components of the sample to separate based on their affinity for the stationary and mobile phases. The choice of solvent affects the resolution and speed of separation in chromatography techniques.
How do you use chromatography to show how many colors were in the solution?
It depends what sort of solution and what sort of chromatography. Assuming it's something simple like ink you'd usually use a piece of paper or filter paper. You'd apply a spot of your analyte (the solution being analysed) at a short distance from the bottom of the paper, then put the paper in a beaker or similar container with a small amount of ethanol, water or another solvent in the bottom. Ensure that the solvent does not go above the level of the spot of analyte. The solvent will be drawn up through the paper by capillary action, and will draw the different parts of the analyte with it and deposit them at different distances from the initial spot. Stop the experiment by removing the paper from the beaker once the solvent front (the horizontal line where the highest wet part of the paper is) reaches the top of the paper.
What happens when paper chromatography is left in the solution?
If paper chromatography is left in the solution, the solvent will continue to move up the paper by capillary action. This can lead to the separation of the components in the mixture to a greater extent. Additionally, the colors may spread out and further separate along the paper.
What is propelling force in paper chromatography?
The propelling force in paper chromatography is capillary action, where the solvent moves through the paper due to the attraction between the solvent and the paper fibers. This causes the components in the sample to separate as they are carried at different rates along the paper.

When more solvent is added to a solution to decrease its concentration it is called?
When more solvent is added to a solution to decrease its concentration, it is called dilution. Dilution involves reducing the concentration of solute particles within the solution by adding more solvent to increase the total volume.

How is paper used in paper chromotagraphy?
Paper chromotagraphy is a technique of separating a solution containing two or more soluble solids. A minute amount of the solution is first dotted on a piece on paper. The paper is then hung above a solvent (such as water or ethanol) just so that the tip of the paper is soaked in the solvent.The solvent then rises upwards and soaks the rest of the paper. This occurs because there is a force of attraction between the solvent and the paper.As the solvent rises, it carries the sample of the initial solution and separates the dissolved solids. The multiple different solids settle at different points on the paper, based on its solubility.The point at which the solvent stops rising upwards is known as the solvent front.
What is the method of Paper chromatography?
Paper chromatography is a technique used to separate and analyze different components of a mixture based on their affinity for a stationary phase (paper) and a mobile phase (solvent). The mixture is applied to a specific point on the paper and then placed in a container with a solvent that moves up the paper via capillary action, carrying the components with it. As the solvent moves, the components of the mixture are separated based on their solubility in the solvent and their interaction with the paper.
What is propelling force in paper chromatography?
The propelling force in paper chromatography is capillary action, where the solvent moves through the paper due to the attraction between the solvent and the paper fibers. This causes the components in the sample to separate as they are carried at different rates along the paper.
What forces the eluting solution to move along the chromatographic support material?
An eluting solvent is then allowed to move up the plate by capillary action, drawing the components of the mixture along by varying degrees.Read more: chromatography
How do most paints dry?
Most paints dry by the action of air vapourising their solvent.
Are enzymes colloid or solutions?
a colloidal solution is defined as ,a solution in which solute in evenly suspended in solvent.For effective enzyme action an aqueous colloidal solution is the utmost necessity in a biochemical pathway.hence enzymes are colloids.
