how will you separate dyes in black ink using chromatography? explain it with the help of diagram?
Answers
Method:
1.Take a thin strip of filter paper.
2.Draw a line on it using a pencil approx. 3 cm above the lower edge.
3.Put a small drop of ink with help of a pen at centre of line and let it dry.
4.Lower the filter paper into a glass jar containing water in such a way that the ink's drop remains just above the water level. Leave it undisturbed.
5.Water rises up in the filter paper. Ink drop splits up into its constituents.
Conclusion:Dye in black ink is a mixture of 2 or 3 colours. The coloured component that is more soluble in water rises faster and in this way the colours get separated.
hi there
Chromatography is a method of separating out materials from a mixture. Ink is a mixture of several dyes and therefore we can separate those colors from one another using chromatography. When ink is exposed to certain solvents the colors dissolve and can be seperated out
hope this ans helps u
