Chromatography

Question 1

What is Chromatography

Answer 1

It is the separation technique in which a mobile phase carrying a mixture moves in contact with a selectively adsorbent stationary phase

Question 2

Name the separation techniques

Answer 2

Chromatography
Infra red Spectrometry
Ultraviolet Spectrometry

Question 3

What are the different Chromatography Techniques

Answer 3

Paper
Thin Layer (TLC)
Column
Gas
HPLC

Question 4

The principle on which all chromatographic separation techniques are based is that….

Answer 4

separation of a mixture of components occurs as a result of selective absorbance of the components of the mixture on a stationary phase while carried by a mobile phase.

Question 5

What spectroscopic method is used to detect heavy metals

Answer 5

Atomic Absorption

Question 6

State the principle of ultra violet absorption spectroscopy

Answer 6

Absorption of UV radiation by molecules results in the promotion of electrons from their ground state energy levels to higher energy levels.

Question 7

What is the principle of infrared spectrometry

Answer 7

molecules absorb infrared radiation of different frequencies.
