Q » What is osmotic pressure and why is it higher in seawater?
03 Nov, 2025
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.
