Skittles
Chromatography is a technique for the separation of a mixture by passing it in solution or suspension through a medium which the components move at different rates.
Aim: to separate the colours from the skittles by using chromatography
Martials:
1. 5 Skittles
2. Water
3. Petri dish
4. Beaker
Process:
Step 1: Get your equipment set up ready to pour 25mls of water into the petri dish with the skittles.
Step 2: Place the skittles into the petri dish around the edges.
Step 4: watch as the water removes the dye from the skittles. See which colour reaches middles fastest.
Step 5: Record your results on the tables below. (forgot to take a photo sorry)
