explain paper chromatography
Answers
There are 2 phases of it:
stationary phase : a solid, or a liquid supported on a solid)
mobile phase: a liquid or a gas
The mobile phase flows through the stationary phase and carries the components of the mixture with it. Different components travel at different rates.

Topic :
"Paper chromatography"
A set of laboratory techniques used for the seperation of mixtures (coloured Chemicals) is called "Chromatography".It works because some components of a mixture are more soluble than others.
In paper chromatography special paper is used to seperate the coloured components in a mixture.
Chromatography only works for soluble dyes, like in food and pen not in dye clothes.
The most soluble dyes move faster on the filter paper than less soluble dyes.
Activity :
Required Things :
- A breaker.
- A Medicine dropper.
- A filter paper.
- A Solution of dye or ink.
Procedure :
- Put the filter paper on the breaker.
- Put a drop of ink in the middle of the paper.
Observation :
Soon you will see different bands of colour on the filter paper. Each band show the presence of a differnet component of the Solutuion.
