Question

Consider the following statements.
(a) Thin layer chromatography is a type of partition chromatography.
(b) Silica gel and alumina are commonly used adsorbents in adsorption chromatography.
(c) In paper chromatography, chromatography paper contains water trapped in it, which acts as stationary phase.
The correct statement(s) is/are:

• A. (a) and (b) only
• B. (b) and (c) only
• C. (b) only
• D. (a), (b) and (c)

Answer 1

The correct option is B (b) and (c) only

• Thin layer chromatography is a type of adsorption chromatography.
• In adsorption chromatography, commonly used adsorbents are silica gel and alumina.
• Paper chromatography is a type of partition chromatography. In this chromatography, a special quality paper known as chromatography paper is used. Chromatography paper contains water trapped in it, which acts as stationary phase.
