What is the purpose of the solvent in paper chromatography?

• To create a chemical reaction

• To dissolve the paper

• To provide color to the mixture

• To separate the components of a mixture based on their solubility and affinity for the solvent.

How does the size of the paper affect the separation in paper chromatography?

• The smaller the paper size, the better the separation in paper chromatography.
