WHat is chromatography?

Chromatography' is an analytical technique commonly used for separating a mixture of chemical substances into its individual components, so that the individual components can be thoroughly analyzed.

Activity - SEperation of black ink using cromatography

The objective of this activity is to separate the various substances that make up a mixture.(black ink) and see them individually

AIM

Filter paper ( or chromatography strips) Black marker small cups or beakers Toothpicks Paper clips Glass rod Water

MAterials required

Steps

Record your observations

Watch carefully as the water rises up on th filter papet

Lower the filter paper into a jar containing water so that the drop of ink on the paper is just above the water level.

IPut a small drop of the marker ink at the centre of the line.Let it dry.

Draw a line on it using a pencil , appox 3 cm above the lower edge.

Take a thin stirp of filter paper

You must have observed that When the water passes through the black ink it takes the pigment colors with it. Some pigments dissolve in water easier and are pulled with the water further up the paper. which gives us our conslusion which is chromatography means– separating the parts of a mixture so that you can see them one at a time.

THANKYOU!
