By the end of this lab, you will see how some materials diffuse through a semipermeable membrane but others do not. the materials that you examine will differ in molecule size. some will be larger and some smaller. formulate an investigative question for this situation

Permeability is defined as the ability of the membrane or material to allow the passage of ions, molecules, and other substances.

The permeability is affected by the molecule size, molar mass, and polarity of the substance.

The investigative question is:

How does the size of the molecule affect the permeability of the membrane?

Permeability is the property of a membrane, which allows the molecules to diffuse through them. The permeability of the membrane is dependent on:

Therefore, permeability is affected by certain factors like molecule size and polarity.
