Basic Concepts of Chromatography
1) Chromatography is a physical method that is used to separate and analyse
__________
a) Simple mixtures
b) Complex mixtures
c) Viscous mixtures
d) Metals
Answer: b
Explanation: Chromatography is a physical method that is used to separate complex
mixtures. The mixture of different components is flushed through the system at
different rates.
2) In which type of chromatography, the stationary phase held in a narrow
tube and the mobile phase is forced through it under pressure?
a) Column chromatography
b) Planar chromatography
c) Liquid chromatography
d) Gas chromatography
Answer: a
Explanation: In Column chromatography, the stationary phase held in a narrow tube
and the mobile phase is forced through it under pressure. It is carried out in a long
glass column having a stop-cock near the bottom.
3) In chromatography, the stationary phase can be ___________ supported on
a solid.
a) a) Solid or liquid
b) Liquid or gas
c) Solid only
d) Liquid only
Answer: a
Explanation: In chromatography, there are two phases namely, stationary phase and
mobile phase. The stationary phase can be solid or a liquid supported on a solid.
4) In chromatography, which of the following can the mobile phase be made
of?
a) Solid or liquid
b) Liquid or gas
c) Gas only
d) Liquid only
Answer: b
Explanation: In chromatography, the mobile phase can be composed of liquid or gas.
It cannot be a solid material.
5) +Which of the following cannot be used as an adsorbent in Column
adsorption chromatography?
