Answer Details
The movement of water across a semi-permeable membrane from a weaker solution to a stronger solution is known as osmosis. In osmosis, water moves across a membrane from a region of high water concentration (weaker solution) to a region of low water concentration (stronger solution) in an attempt to equalize the concentration of solutes on both sides of the membrane. This process continues until the concentration of solutes on both sides of the membrane is the same or until the pressure on the stronger side is too high for water to move.
