Question

The volume of a colloidal particle, $V_c$ as compared to the volume of solute particle in a true solution, $V_S$ could be

• A. V _C/V _S = 1
• B. V _C/V _S = 10²³
• C. V _C/V _S = 10^–3
• D. V _C/V _S = 10³

Answer 1

The correct option is D V _C/V _S = 10³

Diameter of colloidal particles is about 10 times larger than solute particles in a true solution. Hence, volume is about 1000 times greater $(i.e.\frac{V_c}{V_s}={10}^3)$.
