Question:

Which of the following is not an example of lyophobic colloids?

Options:

Gold solution

Sulphur solution

NaCl solution

Blood

Correct Answer:

NaCl solution

Explanation:

Blood, Sulphur solution, and Gold solutions are colloids in which the dispersed phase has an extremely low affinity for the dispersion medium. Once these colloids are separated, the solution cannot be recovered by simply combining the two phases. As a result, they fall within the category of lyophobic colloids.
