Ink is put on a piece of paper, what happens next?

THIS EXPERIMENT WAS PERFORMED AND SENT TO ME BY GURBIR SINGH BAJWA OF GRADE 10



Ingredients


- 1 Thin Strip Of Filter Paper Or Chromatography Paper

- 1 Glass Beaker

- 1 Sketch Pen


STEP


- Take A Thin Strip Of The Filter/Chromatography Paper

- Mark a small point on the paper with a sketch pen

- Then lower the piece of paper into the beaker in a way that the dot is just over the water level

- Leave it undisturbed for a few hours

- The Dot of ink slowly separates upwards, and the constituents of the ink separate out of the ink itself


This is the concept of chromatography,


Gurbir has included a fun fact about the origin of the word, let's see


The word chromatography, comes from the greek term "Chroma" and also the term "Graphian". "Chroma" means color and "Graphian" means to write. The technique was first used to separate colors, hence the name!


Now let's see how this works,


Now, Chromatography is a vast topic, one in which a lot research has been done.


However, in simple terms, chromatography is the separation of a substance by a solvent.


This definition is consistent with the results of gurbir's experiment.


Now, as some of you may know, Ink isn't just one substance, it consists of a very diverse set of dyes and molecules that make it what it is.


Now all of these molecules behave differently ,chemically speaking, some move faster than others.


This difference in movement speed is the reason why some colors in the ink move ahead farther than others.


Now, this is an absolute oversimplification of events. If any readers want to read a little bit more about this, I highly suggest that you check out this article.


Thank you to GURBIR SINGH BAJWA for performing this experiment!
