Question

Examples of lyophilic colloids are

• A. Albumin
• B. RBC
• C. Smoke
• D. Metasulphide

Answer 1

Answer: (A), (B)

RBC

The explanation for correct options-

(A) - Albumin

(B) - RBC

Colloids:

• A colloid is primarily a heterogeneous mixture in which the minute particles of one substance are dispersed in another substance, called the dispersion medium.

Lyophilic colloid:

• If the dispersed phase has an affinity for the dispersion medium, the colloid is called a lyophilic colloid.
• Even if the dispersed phase is separated from the dispersion medium, they can readily be reconstituted by simply mixing them.
• They are difficult to coagulate due to their stable nature. They are also known as intrinsic colloids.
• Examples – Starch, rubber, protein, RBC, and egg albumin.

The explanation for incorrect options.

(C) - Smoke

Smoke is an aerosol of solid particles and liquid droplets that are close to the ideal range of size for Mie scattering of visible light.

(D) - Metasulphide

It is an inorganic compound.

Hence options (A) and (B) are the correct answer.
