# Two different containers full up with pure water and salt water in osmosis. What happens?

I would like to understand what happens when there are two containers which are connected together and separated by only semipermeable membrane. Then in one container I fill up (all the way to the top) pure water and in the second container I put water with a lot of salt ($\ce{NaCl}$). Now In container 2 it said to be an high osmotic pressure.

Then my question is: Is the water in container 1 will drain out / will be pushed out by the osmotic pressure in container 2? (see sections a,b,c below).

■  My question popped up after reading the following things in a book called "RBS - physiology" (6t edition p. 5):

Osmosis is the flow of water across a semipermeable membrane from a solution with low solute concentration to a solution with high solute concentration.

Example of osmosis:

a. Solutions 1 and 2 are separated by a semipermeable membrane. Solution 1 contains a solute that is too large to cross the membrane. Solution 2 is pure water. The presence of the solute in solution 1 produces an osmotic pressure.

b. The osmotic pressure difference across the membrane causes water to flow from solution 2 (which has no solute and the lower osmotic pressure) to solution 1 (which has the solute and the higher osmotic pressure).

c. With time, the volume of solution 1 increases and the volume of solution 2 decreases.
