Question

What is osmotic pressure?

Answer 1

The minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane is known as Osmotic pressure.

$\Pi =CRT$ ------ 1

where,

$\Pi =$ osmotic pressure

$C=$ molarity of solution

$R=$ universal gas constant

$T=$ temperature .
