3. How could you separate the pigments which make up a dye?

4. Separating Compounds: Chromatography

5. Separating Compounds: Chromatography
In an evaporating dish place 2 skittles of the same colour and 1 drop of water
Prepare you filter paper as shown
Put a layer of water in your beaker, about 2 cm
Carefully build up a concentrated dot of dye
Carefully place your filter paper in the water
Do not let the water touch the dye directly!

6. Prepare a piece of filter paper to separate the dye in a pen… choose black and a secondary colour.

7. How could you separate the compound copper chloride?

8. Separating Compounds: Electrolysis

9. Draw a labelled diagram of the experiment
Electrolysis of Copper Chloride
Draw a labelled diagram of the experiment
A good diagram:
Should be drawn with a ruler
Should not be 3D
Should not be shaded
Should be labelled using straight lines
