Question -

The volume of colloidal particle $V_{c}$ as comapred to the volume of solute particle in a true solution $V_{s}$ could be

Options:

A .

\frac{V_{c}}{V_{s}} = 1

B .

\frac{V_{c}}{V_{s}} = 10^{23}

C .

\frac{V_{c}}{V_{s}} = 10^{- 3}

D .

\frac{V_{c}}{V_{s}} = 10^{3}

Answer: Option D
:
D

Diameter of colloidal particle is about 10 times larger than solute particles in a true solution. Hence, volume is about 1000 times greater i.e. $\frac{V_{c}}{V_{s}} = 10^{3}$
