Hi 😁
Aim :To separate colours by using the process of chromatography
Definition :Chromatography is a method of separating out materials from a mixture using liquid
Materials:
1.Boiling tube
2.Filter Paper
3.Water based felt
4.Water
5.Scissors
6.Test Tube stand
7. Ruler
8. pencil
Process :
- Cut your piece of paper with scissors
- Rule a line 1 cm from the bottom of the paper strip
- Put 8 ml of water in boiling tube
- Draw 2 colored pen dots on the line
- Drop the paper strip into the boiling and once it is touching the water at the bottom you can crease the top of the paper over
- Watch and take two photos then observe the chromatography
