Question

Choose the correct statement(s):

Answer 1

Reverse Osmosis
If the pressure applied on the solution side is more than the osmotic pressure of the solution, then the solvent particles will move from solution to solvent side.
\(P_{ext}>\pi\)
Example
Used in desalination of sea-water.
Plasmolysis
When the cell is placed in a solution having its osmotic pressure greater than that of the cell sap, water passes out of the cell due to osmosis.
Consequently, the cell material shrinks gradually. The gradual shrinking of the cell material is called plasmolysis.
