how is the chemical potential of water related to osmosis? course hero

by Abigail Nitzsche Jr. 9 min read

The water potential gradient determines the direction of osmosis. It goes from high to low water potential. This is because n a high water potential area there is a bigger number of free water molecules. Free here means they are not attached to other solute molecules forming a hydration shell.

What determines the direction of osmosis?

The water potential gradient determines the direction of osmosis. It goes from high to low water potential. This is because n a high water potential area there is a bigger number of free water molecules.

How does the water potential gradient affect osmosis?

The water potential gradient determines the direction of osmosis. It goes from high to low water potential. This is because n a high water potential area there is a bigger number of free water molecules. Free here means they are not attached to other solute molecules forming a hydration shell.

What happens when you mix two solutions with the same osmolarity?

If two solutions have the same osmolarity, they are said to be isosmotic. You pour salt on a snail, the water molecules on that snail will stick to the chlorine and sodium ions, and therefore make room for more water, therefore DECREASED the water potential. The lower the more water is being moved.

What happens when the water potential is high or low?

It goes from high to low water potential. Explanation: This is because n a high water potential area there is a bigger number of free water molecules. Free here means they are not attached to other solute molecules forming a hydration shell.
