Question

what's reverse osmosis?​

Answer 1

Answer:

a process by which a solvent passes through a porous membrane in the direction opposite to that for natural osmosis when subjected to a hydrostatic pressure greater than the osmotic pressure.

Answer 2

$\huge{\underline{\sf{\red{Answer-}}}}$

if the external pressure applied on the solution is greater than the osmotic pressure of the solution,then osmosis takes place from region of higher molar concentration to a region of lower molar concentration.this phenomenon is known as reverse osmosis.

• A very wide use of reverse osmosis is obtaining drinking water from sea water.

• it is used for removing the salt from water molecules.
• it is also used in removing of ions.

• this was first searched in 1950.this is done for water filtration.
