Paper Chromatography

What is the principle of paper chromatography?

• Separation of components based on temperature and pressure.

• Separation of components based on size and shape.

• Separation of components based on solubility and affinity for the paper

• Separation of components based on density and viscosity.

What is the mobile phase in paper chromatography?

• Paper

• Water

• Ink

• Solvent or mixture of solvents

What is the stationary phase in paper chromatography?

• The paper itself

• The color of the ink being separated in paper chromatography.

• The mobile phase in paper chromatography.

• The solvent used in the chromatography process.

What are the applications of paper chromatography?

• Separating and analyzing mixtures of colored substances, identifying unknown substances, and determining the purity of a substance.

• Detecting the presence of heavy metals, measuring the viscosity of a liquid, and determining the density of a substance.

• Separating and analyzing mixtures of gases, identifying unknown bacteria, and determining the melting point of a substance.

• Detecting radioactivity, measuring pH levels, and determining the boiling point of a substance.

What are the limitations of paper chromatography?

• High cost, time-consuming process, and limited sample size.

• Limited resolution, low sensitivity, and difficulty in identifying unknown compounds.

• Limited applicability, complex procedure, and requirement of specialized equipment.

• Low reproducibility, susceptibility to interference, and limited separation efficiency.

In paper chromatography, what property of the components determines their movement?

• Density of the stationary phase

• Affinity for the mobile phase and solubility in the stationary phase

• Temperature of the mobile phase

• Size of the components

What is the purpose of the stationary phase in paper chromatography?

• To speed up the separation process.

• To prevent the mixture from evaporating.

• To increase the accuracy of the results.

• To separate different components in a mixture based on their affinity for the stationary phase.

What is the purpose of the mobile phase in paper chromatography?

• To carry the sample components and separate them

• To increase the viscosity of the sample components.

• To prevent the separation of sample components.

• To provide color to the sample components.

What are the different types of paper used in paper chromatography?

• filter paper, chromatography paper, and Whatman paper

• cardstock paper

• newsprint paper

• tissue paper

How does the polarity of the mobile phase affect the separation in paper chromatography?

• Increasing the polarity of the mobile phase decreases the separation in paper chromatography.

• The polarity of the mobile phase has no effect on the separation in paper chromatography.

• Decreasing the polarity of the mobile phase increases the separation in paper chromatography.

• The polarity of the mobile phase affects the separation in paper chromatography by influencing the rate at which the components move and the distance they travel on the paper.
