A » Osmotic pressure is the pressure required to prevent the flow of water through a semipermeable membrane that separates solutions of different concentrations. It is higher in seawater due to its elevated salt content, which increases solute concentration and thus the osmotic pressure needed to counterbalance the natural movement of water into the saltier solution. This principle is crucial in water purification processes like reverse osmosis.

A »Osmotic pressure is the pressure required to prevent water flow into a solution through a semipermeable membrane. Seawater has higher osmotic pressure due to its high salt concentration, making it harder to purify. This pressure must be overcome in desalination processes, such as reverse osmosis, to produce freshwater.
