Question

What is chromatography?​

Answer 1

Answer:

a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates

Answer 2

Chromatography is a process of separation of similar substances from their mixture solution.

Explanation:

• Chromatography has been defined as primarily a separation process which is used for the separation of essentially molecular species. It is a physical method of separation.
• It is based on the principle of selective distribution of the components of a mixture between two phases- a Stationary phase(SP) and Mobile Phase(MP). The SP may be solid or liquid while MP is liquid or gas.
• In this method mixture of similar substances are passed through a column or along a plane where the substance is continuously exchanged and equilibrated between two phases.
