Before we tell you what chromatography is, we'll illustrate it using the following question
and diagram which shows a piece of paper marked with 4 substances that was then placed into
a cup of water.
When the paper begins to absorb the water, molecules within the substances will begin
to separate as they get carried up by the water.
These materials were used to carry out the technique known as ... paper chromatography,
which basically, is a technique used to separate molecules.
So, if you saw the following diagram, do you think you can answer the following question?
If so, write your answers in the comments section below this video.
