Chromatography is a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.
Aim: To separate the colours from the skittles by using chromatography.
Materials:
1. 5 Skittles
2. Water
3. Petri dish
4. Beaker
Process:
step 1: Get your equipment set up ready to pour the 50mls of water into the petri dish with the skittles.
step 2: Place the skittles into the petri dish around the edges.
step 3: Pour 50mls water gently into the middle of the petri dish.
step 4: Watch as the water removes the dye from the skittles. See which colour makes the middles fastest.
step 5: Record your results on the table below.
