How do you identify the component with the greatest affinity for the mobile phase in paper chromatography
component with the greatest affinity for the mobile phase will travel the furthest in paper chromatography
what is the mobile phase in paper chromatography
In paper chromatography, the mobile phase is always the solvent (water, in this case), while the stationary phase is the paper.
retention factor formula
Rf=distance traveled by the compound / distance traveled by the solvent front
what does the Rf mean for the affinity to the solvent
A lower Rf value means that the substance has a lower affinity for the solvent
Suggest a limitation of the paper chromatography described as a separating technique.
It only works for colored components;
Separation might be incomplete/spots can be mixtures of components with similar RFRF;
Only allows the separation of a small amount of sample;
Time-consuming technique.
describe the arrangement of molecules at a liquid state
