Paragraph: Osmosis is a process of movement of solvent particles from a region of lower to higher concentration through semi permeable membrane. The pressure exerted by the liquids on semi permeable membrane at the time of equilibrium is called osmotic pressure. If the pressure more than osmotic pressure is applied at the more concentration side, reverse osmosis takes place, which is used for the purification of wate

Options

  1. AIf semi permeable membrane is permeable to only H ₂ O , level of liquid in the left arm will decrease
  2. BIf membrane is permeable to H ₂ O , Cl ⁻ and Na ⁺ all, the level of liquid in two arms is different
  3. CIn the reverse osmosis process water will move from NaCl side to H ₂ O side
  4. Dall of these

Correct answer

C. In the reverse osmosis process water will move from NaCl side to H ₂ O side

Step-by-step solution

In reverse osmosis water moves from more concentrated to less concentrated solution
