Question

Which of the following is an example of associated colloid?

• A. Protein $+$ water
• B. Soap $+$ water
• C. Rubber $+$ benzene
• D. $A{s}_2{O}_3+Fe{\left(OH\right)}_3$

Answer 1

The correct option is B Soap $+$ water

Association colloids are micro-heterogeneous systems in which the particles of the colloidal dispersed phase (micelles) are formed by the agglomeration of molecules or ions of the substance dissolved in the dispersion medium.

Examples are soap, synthetic detergents, organic dyes, tanning agents and alkaloids.

Hence, the correct answer is option $\text{B}$.
