BASIC TLC

What is the stationary phase in thin layer chromatography?

• The solvent system

• The TLC plate

• The mobile phase

• The sample solution

What is the purpose of the mobile phase in thin layer chromatography

• To dissolve the sample

• To bind to the stationary phase

• To carry the sample along the TLC plate

• To visualize the separated components

Which of the following is not a factor that affects the separation of compounds in thin layer chromatography?

• The polarity of the stationary phase

• The polarity of the mobile phase

• The size of the sample molecules

• The temperature of the developing chamber

What is the purpose of visualizing the separated components in thin layer chromatography?

• To determine the Rf value of each component

• To identify the components in the sample

• To determine the purity of the sample

• To determine the concentration of the sample

How is the Rf value calculated in thin layer chromatography?

• Distance traveled by sample / distance traveled by solvent

• Distance traveled by solvent / distance traveled by sample

• Distance traveled by sample x distance traveled by solvent

• Distance traveled by solvent x distance traveled by sample
