Many old time folk remedies made use of the priciples of diffusion and osmosis. Suppose you had a sliver of wood or another small foreign object embedded under your skin. It is slightly swollen and hurts. Your grandma or older neighbor tells you to soak the affected part in salt water. Using your knowledge of diffusion/osmosis, how do you think this would affect the injury? Will it help you get the sliver out?

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
