Pure water can be obtained from seawater by _____.

Options

Acentrifugation
Bplasmolysis
Creverse osmosis
Dsedimentation

Correct answer

C. reverse osmosis

Step-by-step solution

When the external pressure, greater than the osmotic pressure, is applied on a solution separated by semipermeable membrane, the transfer of solvent particles take place from higher concentration to lower concentration. This phenomenon is known as reverse osmosis. So, the seawater can be converted to pure water by reverse osmosis.
