How could you separate the pigments which make up a dye?
Separating Compounds: Chromatography
Separating Compounds: Chromatography 1. In an evaporating dish place 2 skittles of the same colour and 1 drop of water 2. Prepare you filter paper as shown 3. Put a layer of water in your beaker, about 2 cm 4. Carefully build up a concentrated dot of dye 5. Carefully place your filter paper in the water Do not let the water touch the dye directly!
Prepare a piece of filter paper to separate the dye in a pen… choose black and a secondary colour.
How could you separate the compound copper chloride?
Separating Compounds: Electrolysis
Electrolysis of Copper Chloride Draw a labelled diagram of the experiment A good diagram: ü Should be drawn with a ruler ü Should not be 3 D ü Should not be shaded ü Should be labelled using straight lines
