Question

which of the following method seperate both ionic & non ionic impurities from water
1. Electrodialysis
2. Reverse osmosis
3. Deionization
4. all of the above​

Answer 1

The correct answer is option (2.) Reverse osmosis.

Explanation:

• Reverse osmosis is the method which separates both ionic & non ionic impurities from water.
• The process of Reverse osmosis is also known as Super or Hyper Filtration.
• It is 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.
• It is a system removes sediment and chlorine from water with a prefilter before it forces water through a semipermeable membrane.
