Chromatography:

Chromatography:

Aim: To separate the difference pigments in inks using paper chromatography.

Method: 1. cut a piece of filtered paper long enough to reach the bottom of your test tube. 

2. Rule a line in pencil approximately 2 cm from the bottom of your piece of paper. 

3. Fill your beaker with enough chromatography solution to fill your beaker to a depth of 1 cm. 

4. Place a dot of ink above the ruled lone on your filtered paper. You need to produce a concentrated dot of ink so repeated applications mat be necessary. 

5. Suspend the suspend the strip of paper from the pencil stick. You may need to use adhesive tape to stop it from falling into the solution. 

6. Wait to see what happens. It is important that you do not disturb the beaker. If the solution comes in contact with the ink dot, ink will run down into solution, rather than move up the filtered paper. 

Result: 

Discussion:  When we put the solute which was filtered paper with a ink dot in the solvent which was water. It turned the ink drowned down that made a cool design when you left for a few minutes.
