Answer the following questions given below:
Kamali wanted to separate the different colours in her marker ink. she took a strip of filter paper and drew a line near the bottom with a pencil. On this line, she placed a small spot of ink. Then, she carefully placed the strip in a beaker containing a little solvent (water or alcohol), making sure the ink spot did not touch the liquid. As the solvent moved up the paper, she observed that the ink separated into different colours along the strip.
1. Which property of the components is used in this separation?
2. What does she observe on the paper strip after the experiment?
3. What is the stationary phase in this experiment?
