Vedclass · Answer

(B) Colloidal solutions exhibit colligative properties due to the presence of particles,although the values are small compared to true solutions.An ordinary filter paper has large pores that allow colloidal particles to pass through easily; therefore,it cannot stop the flow of colloidal particles.According to the Hardy-Schulze rule,the flocculating power of an ion increases with the increase in the magnitude of its charge. Thus,$Al^{3+}$ has a much higher flocculating power than $Na^{+}$.Colloidal particles exhibit Brownian motion due to the unbalanced bombardment of the particles by the molecules of the dispersion medium.Therefore,statement $B$ is incorrect.

Which of the following statements regarding colloidal solutions is $INCORRECT$?
