Question

The volume of colloidal particle $V_c$ as comapred to the volume of solute particle in a true solution $V_s$ could be

• 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 1

The correct option is D $\frac{V_c}{V_s}={10}^3$

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. $\frac{V_c}{V_s}={10}^3$
