Assertion : Reverse osmosis is used to purify sea water.
Reason : Solvent molecules pass from concentrate solution to pure solvent through semipermeable membrane if high pressure (> π) is applied on solution side
Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules. In Reverse osmosis, molecules are forced through a semi-permeable membrane to form a less concentrated solution.
