A
Dissolution the molecules can move with
2
Q
What is the stationary phase
A
Chromatography paper
3
Q
What happens if a chemical spend more time in the mobile phase than the stationary phase
A
They will move further
4
Q
What does the amount of time molecule spend on each phase depend on
A
How soluble they are in the solvent
how attracted they are to the paper
5
Q
What will happen to molecules with higher solubility
A
Spend more time in the mobile phase
6
