Assertion : Chromatography in general involves a mobile (a gas, a liquid or a supercritical fluid) and a stationary phase (like Al_(2)O_(3) column). Reason : A component which is less soluble in stationary phase takes longer time to travel through it than the component which is more soluble in stationary phase.

1.	Assertion : Chromatography in general involves a mobile (a gas, a liquid or a supercritical fluid) and a stationary phase (like Al_(2)O_(3) column). Reason : A component which is less soluble in stationary phase takes longer time to travel through it than the component which is more soluble in stationary phase.
Answer» If both assertion and reason are true and reason is the correct explanation of assertion . IFBOTH assertion and reason are true but reason is not the correct explanation of assertion If assertion is true but reason is false If both assertion and reason are false. Solution :A component which is quite soluble in the sationary phase, TAKES longer time to TRAVEL through it than a component which is not very soluble in the STATIONARY phase but very soluble in the MOBILE phase.
