If a semipermeable membrane separates a 4 percent salt solution on the right side from a 12 percent salt solution on the left side, water will move from the area of lower solute concentration (the 4 percent solution) to the area of higher solute concentration (the 12 percent solution) in an attempt to equalize the solute concentrations on both sides. This process, known as osmosis, will continue until equilibrium is reached, resulting in an increase in the salt concentration on the right side and a decrease on the left side.
The process you are referring to is called dialysis. It involves using a semipermeable membrane to separate molecules based on their size in a solution or colloid. The smaller molecules can pass through the membrane, while the larger ones are retained, allowing for purification or concentration of the solution.
osmotic pressure
The more concentrated solution is hypertonic and osmotic pressure (a hydrostatic force whose sole purpose in life is to make concentrations equal) tends to move solvent into the more concentrated solution. It will stop rising when either a) the solution concentrations are the same on both sides of the membrane, or b) when the osmotic pressure becomes equal to the ambient air pressure.
To prove that a specific solute can diffuse through a semipermeable membrane, you could set up an experiment where the solute is placed on one side of the membrane, and a solution without the solute is on the other side. Over time, you would measure the concentration of the solute on both sides of the membrane. If the concentration increases on the side without the solute, it indicates that diffusion has occurred. To disprove diffusion, you would find that the concentration remains unchanged on the opposing side, suggesting that the solute cannot pass through the membrane.
The term for the diffusion of water across a semipermeable membrane is osmosis. Osmosis is when the molecules of a solvent move from a less concentrated solution to a more concentrated one. This equalizes the concentrations on each side of the member.

That pressure is called osmotic pressure. It is the pressure needed to prevent the flow of solvent molecules from a less concentrated solution to a more concentrated solution through a semipermeable membrane.

No, in osmosis the solvent (usually water) moves from an area of lower solute concentration to an area of higher solute concentration across a semipermeable membrane in an attempt to equalize the solute concentrations on both sides of the membrane.

It's the hypertonic solution. It contains a higher osmole concentration than the fluid present inside the cell "the cytosol" ,so the water inside the cells comes out in order to dilute the hyper-tonic solution in an attempt to make a balance between the two sides of the semipermeable membrane ( The cell membrane is a semipermeable membrane that separate the fluid present inside the cell and that outside it).
Semi permeable membrane means a very thin layer of material which allows some molecule to pass through them and prevent some molecule to pass through them. Osmosis is the passage of water from a dilute solution via a membrane which is semi permeable to a more concentrate solution. So the membrane should be semi-permeable so as to only allow the movement of H2O molecules and not the other molecules of the mixture.
movement of a solvent (as water) through a semipermeable membrane (as a living cell) into a solution of higher solute concentration that tends to equilize the concentration of solute on the two sides of the membrane.

Osmosis occurs when there are two solutions of different concentration strength separated by a semipermeable membrane. The membrane must allow water to cross, but not the solutes. Water will then move from the solution of lower concentration strength across the membrane to the solution of higher concentration strength. This movement of water is called osmosis.

In this situation, the two solutions are said to be isotonic. This means that they have the same concentration of solutes and the same osmotic pressure. As a result, there is no net movement of water across the membrane.
