    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 2005]

    A)                 \[\frac{{{V}_{C}}}{{{V}_{S}}}\tilde{}1\]  

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

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

    D)                 \[\frac{{{V}_{C}}}{{{V}_{S}}}\tilde{}{{10}^{3}}\]

    Correct Answer: D

    Solution :

                    \[\frac{{{V}_{c}}}{{{V}_{s}}}=\frac{{{10}^{-5}}}{{{10}^{-7}}}\approx {{10}^{3}}\]
