What does chromatography mean and what is a colloid?
Question asked by: knowitall
Chromatography is the process of separating an ink or dye into its separate colours through using water to spread out the different layers.
A colloid is a mix of a substance in one state (solid, liquid or gas) in another in another state.
Therefore you could have a liquid-gas colloid or a water-solid colloid and so on.
For instance an Aero chocolate bar is a gas-solid colloid as it has bubbles of air inside solid chocolate.
