What Adsorption and differential movement means in Chemistry A-Level, as defined for OCR.
Definition of Adsorption and differential movement
Check what you remember
Read the wording for your board, then hide it and explain Adsorption and differential movement in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Separation depends on how strongly each component is adsorbed on the stationary phase compared with how readily it moves with the mobile phase, so components travel at different rates and separate.
