Mobile phase can be a gas.
Stationary phase is a finely divided solid adsorbent.
Paper chromatography is an example of partition chromatography.
Separation depends upon equilibration of solute between a mobile and a stationary phase.
The correct option is B. Stationary phase is a finely divided solid adsorbent. The statement (B) is not true about partition chromatography. Stationary phase may/may not be a finely divided solid adsorbent. In paper chromatography, paper is used as the stationary phase and is not finely divided. The separation of the components from the sample mixture is carried out by the process of partition of the components between two phases. Both phases are in liquid form. In this process, the immiscible solid surface coated with the liquid surface on the stationary phase is in the mobile phase. The liquid surface is immobilized by a stationary phase, which results in making it a stationary phase. Types of Partition Chromatography: Liquid-liquid Chromatography and Gas-liquid Chromatography
