Question : What is the principle of reverse osmosis?

1.	Question : What is the principle of reverse osmosis?
Answer» Solution :Reverse Osmosis follows the same principles of osmosis, but in the reverse direction. In this process MOVEMENT of water is reversed by applying pressure to FORCE the water against a concentration gradient of the solution. 2. In reverse osmosis the water molecules MOVE from the lower concentration (salt water = hypertonic ) to higher concentration (pure water = hypotonic ) through a selectively PERMEABLE membrane. 3. Use : Reverse osmosis is USED for purification of drinking water and desalination of seawater .
