Question

Assertion : Reverse osmosis is used in the desalination of sea water.
Reason : When pressure more than osmotic pressure is applied, pure water is squeezed out of the sea water through membrane.
A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

Answer 1

Correct Answer - A
If a pressure large than the osmotic pressure is applied to the solution side, the pure solvent flows out of the solution through semi-permeable membrane and this phenomenon is called as reverse osmosis.
