Urea and glucose

Vedclass · Answer

(B) Osmotic pressure $(\pi)$ is a colligative property,which depends on the number of particles in the solution. $\pi = iCRT$,where $i$ is the van't Hoff factor. For urea $(NH_2CONH_2)$ and glucose $(C_6H_{12}O_6)$,both are non-electrolytes,so $i = 1$. For sodium chloride $(NaCl)$,it ionizes as $NaCl \rightarrow Na^+ + Cl^-$,so $i = 2$. Since urea and glucose have the same van't Hoff factor $(i = 1)$ and the same concentration $(C)$,they will produce equal osmotic pressure.

One mole each of urea,glucose,and sodium chloride were dissolved in one litre of water. Equal osmotic pressure will be produced by solutions of
