The volume of a colloidal particle, \[{{V}_{C}}\] as compared to the volume of a solute particle in a true solution \[{{V}_{S}},\] could be     AIEEE  Solved  Paper-2005

A) \[\frac{{{V}_{C}}}{{{V}_{S}}}\approx {{10}^{3}}\]

B)                        \[\frac{{{V}_{C}}}{{{V}_{S}}}\approx {{10}^{-3}}\]

C) \[\frac{{{V}_{C}}}{{{V}_{S}}}\approx {{10}^{23}}\]            

D)        \[\frac{{{V}_{C}}}{{{V}_{S}}}\approx 1\]

Correct Answer: A

Solution :

Size of colloidal particles = 1 to 1000 nm (say 10 nm) Size of true solution particles Thus,
