Paper Chromatography Concepts and Applications

Front

What is the primary purpose of using a solvent in paper chromatography?

Back

To separate the components of a mixture.

Front

What might happen if the paper used in chromatography is not properly dried before use?

Back

The components will not separate properly.

Front

What term describes the distance traveled by the solvent in paper chromatography?

Back

Solvent front.

Front

What role does the mobile phase play in paper chromatography?

Back

It carries the components of the mixture along the stationary phase.

Front

Why is it important to mark the initial spot of the sample on the chromatography paper?

Back

To measure the distance traveled by the solute.

Front

Define 'stationary phase' in the context of paper chromatography.

Back

The phase that does not move and is typically the paper itself.

Front

What is the 'mobile phase' in paper chromatography?

Back

The solvent that moves through the stationary phase carrying the components of the mixture.

Front

Explain the concept of 'retention factor' (Rf) in chromatography.

Back

The ratio of the distance traveled by the solute to the distance traveled by the solvent front.

Front

What factors can affect the separation of components in paper chromatography?

Back

Solvent type, paper type, temperature, and sample concentration.

Front

How does the polarity of the solvent affect the separation in paper chromatography?

Back

Different polarities can lead to different interactions with the components, affecting their movement.
