Q. The volume of colloidal particles $V_{c}$ as compared to the volume of solute particles in true solution $V_{s}$ could be :
A) ∼1
B) $\sim 10^{3}$
C) $\sim 10^{2}$
D) $\sim 10^{- 3}$
Explanation
(b)
$\frac{V_{c}}{V_{s}} = \frac{4/3\pi r_{c}^{3}}{4/3\pi r_{s}^{3}} = \frac{r_{c}^{3}}{r_{s}^{3}} = \left( \frac{10}{1} \right)^{3} = 10^{3}$
