Question

Match the statement given in column I with the phenomenon given in column II.

No	Column I		Column II
$\left(i\right)$	Dispersion medium moves in an electric field	$\left(a\right)$	Osmosis
$\left(ii\right)$	Solvent molecules pass through semipermeable membrane towards solvent side	$\left(b\right)$	Electrophoresis
$\left(iii\right)$	Movement of charged colloidal particles under the influence of applied electric potential towards oppositely charged electrodes	$\left(c\right)$	Electroosmosis
$\left(iv\right)$	Solvent molecules pass through semipermeable membranes towards solution side	$\left(d\right)$	Reverse osmosis

Answer 1

$\left(i\right)\to \left(c\right)$

Electroosmosis is the motion of liquid induced by an applied potential across a porous material, membrane, etc. The dispersion liquid moves according to the electric field.


$\left(ii\right)\to \left(d\right)$

Reverse osmosis is the process of forcing a solvent from a region of high solute concentration to a region of low-solute concentration through a semipermeable membrane by applying a pressure in excess of the osmotic pressure.

$\left(iii\right)\to \left(b\right)$

Electrophoresis is a separation technique that is based on the mobility of ions in an electric field. Positively charged ions migrate towards a negative electrode and negatively charged ions migrate toward a positive electrode.


$\left(iv\right)\to \left(a\right)$

Osmosis is the process where solvent molecules move through a semipermeable membrane from a dilute solution/solvent into a more concentrated solution. So, the solvent molecules pass to the solution side under a semi-permeable membrane.
