Sea water is desalinated to get fresh water by which of the following methods?
Answer & explanation
Correct answer: option 1
If external pressure applied to the solution is more than osmotic pressure, then solvent molecules move from solution to solvent and this phenomenon is known as Reverse Osmosis (R.O.).
This process can be used to obtain pure water from seawater. Pure water is squeezed out of seawater by R.O.
