Question

In column chromatography, the separation of a mixture relies heavily on the selective interactions with the stationary phase. Identify the physical states of the mobile and stationary phases respectively in standard column chromatography:

Prashant Kotian · Accepted Answer

Correct answer: B. Column chromatography involves the separation of a mixture over a column of solid adsorbents (stationary phase like Alumina or silica gel) through which a liquid or mixture of liquids (mobile phase) is allowed to flow down. Thus, the mobile phase is liquid and the stationary phase is solid.
