Journal Entry:

What are some ways to separate molecules out of a solution?   

Learning Intentions

• We will learn what chromatography is, its purpose and the necessary components.

• We will learn how solutes can be separated by chromatography based on intermolecular interactions.

• We will learn how to design a separation experiment using paper chromatography to explore the relative strength of interactions among and between components.

Closing Task:

You can design a separation experiment using paper chromatography to explore the relative strength of interactions among and between components.

Content Standards being covered:

 Solutions are homogenous mixtures in which the physical properties are dependent on the concentration of the solute and the strengths of all interactions among the particles of the solutes and solvent. (EK 2.A.3)
