Reverse osmosis is normally used for the_______________?
Correct answer: D. Desalination of brackish water to produce potable (drinking) water
- A. Separation of isotopes of uranium from gaseous uranium hexafluoride
- B. Separation of helium from natural gas
- C. Purification of oxygen
- D. Desalination of brackish water to produce potable (drinking) water
Explanation
Reverse osmosis forces water through a semipermeable membrane while retaining dissolved salts, so it is widely used to desalinate brackish water for drinking. Uranium isotope separation and gas purification use different separation methods.
