Let’s Go With The Flow
A Review of Osmosis and Diffusion
Last week we discussed the two passive processes known
as osmosis and diffusion.
Let’s see if you remember the difference between the two!

Solute of some type was added to beaker A. Now which beaker has the
higher concentration of water

In order to bring the two beakers “closer” in terms of their concentration of water, you
could…

This Next Question Is Tricky!Put Your Thinking Caps On!!!
Let’s assume there are ten solute particles in beaker A. How many solute particles would you add to beaker B in order to create two solutions
with equal concentrations?
