Answered by admin @
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.
