Question 1:

Which chromatography technique uses a mobile phase consisting of a gas?

Explanation: Gas Chromatography is the chromatography technique that uses a mobile phase consisting of a gas. It is commonly used to separate and analyze volatile compounds in a mixture.

Question 2:

Which chromatography technique uses a mobile phase consisting of a liquid?

Explanation: Liquid Chromatography is the chromatography technique that uses a mobile phase consisting of a liquid. It is widely used for the separation and analysis of various compounds in different sample matrices.

Question 3:

Which chromatography technique is commonly used in forensic analysis and drug testing?

Explanation: Gas Chromatography is commonly used in forensic analysis and drug testing due to its ability to separate and identify volatile compounds present in complex mixtures.

Question 4:

Which chromatography technique is based on the differential partitioning of components between a stationary phase and a mobile phase?

Explanation: Both Gas Chromatography and Liquid Chromatography are based on the differential partitioning of components between a stationary phase and a mobile phase. This separation principle allows the separation and analysis of complex mixtures.

Question 5:

Which chromatography technique is commonly used for the analysis of pigments in plants and dyes in textiles?

Explanation: Thin-layer Chromatography is commonly used for the analysis of pigments in plants and dyes in textiles. It involves the separation of components on a thin layer of adsorbent material.
