Which separation technique is used to separate different pigments in a mixture based on their affinity for a stationary phase and a mobile phase?
-
Chromatography
- Filtration
- Decantation
- Distillation
The correct answer is: A
Explanation
Chromatography is a separation technique used to separate and analyze components of a mixture based on their differential partitioning between a stationary phase (e.g., paper or a column) and a mobile phase (e.g., solvent). Different components move at different rates, leading to separation.
