Vedclass · Answer

(B) Colloidal particles are aggregates of molecules or ions with diameters ranging from $1 \ nm$ to $1000 \ nm$. Because colloidal particles are much larger than the solute particles in a true solution,the number of particles in a given mass of colloid is much smaller than in a true solution. Since osmotic pressure is a colligative property and depends on the number of particles,the osmotic pressure of a colloidal solution is of a lower order than that of a true solution at the same concentration. Therefore,the statement in option $B$ is $INCORRECT$.

Among the following,the $INCORRECT$ statement about colloids is
