Question:

$\text{What is a solution that isn't a lyophilic colloid?}$

Options:

1. $\text{Milk}$
2. $\text{Gum}$
3. $\text{Fog}$
4. $\text{Blood}$

Solution:

$\text{HINT: Organic sols are usually lyophobic.}$ $\text{Explanation:}$ $\text{Lyophilic colloid: Lyophilic colloids are the colloidal solution in which the dispersed phase or the particles have a very strong affinity with the liquid.}$ $\text{Sols is that if the dispersion medium is separated from the dispersed phase (say by evaporation), the sol can be reconstituted by simply remixing with the dispersion medium. These sols are also called reversible sols.}$ $\text{Fog is colloid in which the dispersed phase is liquid water droplet and the dispersion phase is gas. We cannot separate the water droplet from gas and cannot be remixed, so fog is not a lyophilic colloid}$
