Rainbow Paper - Science

 Aim: To Separate colours by using the process of chromatography.

Definition: Chromatography is a method of separating out materials from a mixture using a liquid.

Materials;

1. Boiling Tube
2. Water
3. Filter Paper
4. Water Based Felt
5. Scissors
6. Test Tube Stand
7. Ruler
8. Pencil

Process;

1. Cut up a piece of paper with your scissors.
2. Pule a 1cm line at the bottom of your paper strip.
3. Put 8mL of water into the bottom of your boiling tube.
4. Draw two coloured dots on the pencil line.
5. Drop the paper strip into the boiling once it is touching the water at the bottom you can crease the top of the paper over.
6. Watch, take 2 photos and observe the chromatography process on your paper.

Definitions:

Capillary Action :Capillary action is the process of a liquid flowing in narrow spaces without the assistance of, or even in opposition to, external forces like gravity

Filter Paper : Filter paper is a semi-permeable paper barrier placed perpendicular to a liquid or air flow. It is used to separate fine solid particles from liquids or gases.

Solvent : A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.
