Vedclass · Answer

(B) The osmotic pressure $\pi$ is given by the formula $\pi = iCRT$,where $i$ is the van't Hoff factor,$C$ is the molarity,$R$ is the gas constant,and $T$ is the temperature.For $NaCl$ (strong electrolyte),$i = 2$ (dissociates into $Na^+$ and $Cl^-$). Thus,$\pi_a = 2 	imes 2 \ RT = 4 \ RT$.For glucose (non-electrolyte),$i = 1$. Thus,$\pi_b = 1 	imes 1 \ RT = 1 \ RT$.For urea (non-electrolyte),$i = 1$. Thus,$\pi_c = 1 	imes 2 \ RT = 2 \ RT$.Comparing the values,the glucose solution has the minimum osmotic pressure.
