Understanding Dye Separation in Chromatography

Front

What is chromatography?

Back

A technique used to separate mixtures into their individual components.

Front

What is the role of the chromatography paper?

Back

It acts as a medium that absorbs the dye and allows for separation based on molecular properties.

Front

What is a dye?

Back

A substance used to add color to materials, often made of small molecules.

Front

What does it mean for a dye to have small molecules?

Back

It means the dye can move more easily through the chromatography paper.

Front

What is the effect of water in chromatography?

Back

Water acts as a solvent that helps carry the dye molecules up the paper.

Front

Why do different dyes travel different distances on chromatography paper?

Back

Because they have different sizes and properties that affect their movement.

Front

What is molecular size?

Back

The size of a molecule, which can affect how it interacts with other substances.

Front

What happens when a dye is mixed with water?

Back

The dye dissolves and can move with the water up the chromatography paper.

Front

What is the significance of the distance traveled by a dye?

Back

It indicates the size and properties of the dye molecules.

Front

What does it mean for a dye to be attracted to the paper?

Back

It means the dye molecules have a stronger interaction with the paper than with the solvent.
