Solution

Correct Answer:

All of these

Reverse Osmosis (RO) occurs when an external pressure greater than the osmotic pressure is applied to the concentrated solution side.

  • Process: Solvent (water) is forced to move through the semipermeable membrane from the concentrated side to the dilute/pure side.
  • Applications:
  1. Desalination: Removing salts from seawater to produce drinking water.
  2. Industrial Concentration: Concentrating juices or milk by removing excess water.
  3. Medicine: Components of portable dialysis units also utilize RO-related membrane technology for purification.
