Diluted experiment

Equipment:
pipette
Test tube
test tube rack
measuring cylinder 
tweezers

Method:
Fill each test tube with 5 ml of water but the first one filled with 10 ml of water add on small purple crystal give it a little stir now the tube is concentrated.  Then add 5 mill from the first tube (the purple one) and add it to the second one and wait for it to dissolve fully next add 5 ml from the second tube and add it to the third tube and repeat till you reach the last tube this is called dilution. 

Result:
In font of you you would have a ombre affect going down the line 
of test tubes.

Definitions:
Concentration:
In chemistry, concentration refers to the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration usually is expressed in terms of mass per unit volume.

Dilution:
The action of making a liquid more dilute.
