A) \[N{{a}^{+}}\]
B) \[C{{l}^{-}}\]
C) \[{{\tan }^{-1}}\left[ \frac{{{p}^{2}}+PQ+{{Q}^{2}}}{PQ} \right]\]
D) \[{{\tan }^{-1}}\left[ \frac{{{p}^{2}}+{{Q}^{2}}-PQ}{PQ} \right]\]
Correct Answer: B
Solution :
For true solution, the diameter range is 1 to \[\text{1}0\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\] and for colloidal solution, is 10 to\[\text{1}000\text{ { }\!\!\mathrm{\AA}\!\!\text{ }}\] \[\therefore \] \[\frac{{{V}_{C}}}{{{V}_{s}}}=\frac{4/3\pi r_{c}^{3}}{4/3\pi r_{s}^{3}}={{\left( \frac{{{r}_{c}}}{{{r}_{s}}} \right)}^{3}}={{\left( \frac{10}{1} \right)}^{3}}={{10}^{3}}\]You need to login to perform this action.
