1. Paper Chromatography

Chromatography is a technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. The mobile phase may be either a liquid or a gas, while the stationary phase is either a solid or a liquid

Quadrant - IV (MCQs)

. What is the primary principle behind paper chromatography?

A: Adsorption B: Absorption C: Solubility D: Diffusion

What is used as the stationary phase in paper chromatography?

A: Water B: A special type of paper C: Gas D: A liquid solvent

Which of the following is the mobile phase in paper chromatography?

A: Solid adsorbent B: Water C: Organic solvent or mixture D: A paper strip

What is the role of the solvent in paper chromatography?

A: To separate components based on their size B: To dissolve the analytes and carry them along the stationary phase C: To act as a solid adsorbent D: To bind with the components of the mixture

What is the role of the solvent in paper chromatography?

A: To separate components based on their size B: To dissolve the analytes and carry them along the stationary phase C: To act as a solid adsorbent D: To bind with the components of the mixture

What term is used to describe the distance the component travels compared to the distance the solvent travels?

A: Rf value B: pH value C: Concentration gradient D: Retention factor

Which of the following factors affect the rate at which a component moves in paper chromatography?

A: The polarity of the component B: The temperature of the system C: The type of solvent used D: All of the above

Paper chromatography is primarily used to separate----

A: Gases B: Ions C: Liquid mixtures D: Solid mixtures

Which of the following is the most common use of paper chromatography in laboratories?

In paper chromatography, what happens when the components in a mixture have a similar affinity for the stationary phase

A: They will separate easily B: They will move at similar rates C: The solvent will stop moving D: The stationary phase will degrade

What is the typical outcome when a mixture of substances is subjected to paper chromatography

A: The components will completely dissolve in the solvent B: The components will separate into distinct spots C: The mixture will turn into a single homogeneous solution D: All the components will remain at the start line
