$A$ child wanted to separate the mixture of dyes constituting a sample of ink. He marked a line by the ink on the filter paper and placed the filter paper in a glass containing water as shown in the figure. The filter paper was removed when the water moved near the top of the filter paper.
$(i)$ What would you expect to see,if the ink contains three different coloured components?
$(ii)$ Name the technique used by the child.
$(iii)$ Suggest one more application of this technique.

(N/A) $(i)$ If the ink contains three different coloured components,we would expect to see three different coloured bands on the filter paper at different heights,as each component travels at a different speed depending on its solubility in the solvent.
$(ii)$ The technique used is Chromatography.
$(iii)$ One more application of this technique is to separate pigments present in natural colours (e.g.,chlorophyll) or to separate drugs from blood.
