Perform an activity to obtain colored components or dye from black ink by the process of chromatography.
Chromatography - It is the technique for the separation of a mixture by passing it in the solution or suspension through a medium in which the components move at different rates. It is the method based on the difference in the rate of adsorption of various components of a mixture on a suitable adsorbent.
Activity:
Observation:
1. Ink that we use has water as the solvent and the dye is soluble in it and so when the water rises on the filter paper it takes along with it the dye particles.
2. Yes, different coloured spots of dyes are obtained because a dye is a mixture of two or more colours.
Final Conclusion :
Since the ink is a mixture of two or more colours so the more soluble colour rises faster and gets separated.
