Question

Which of the following is not a Lyophilic

colloid?

a. Gold Sol b. Gelatin

c. Starch d. Haemoglobin ​

Answer 1

Gold Sol is not a Lyophilic Colloid.

Reason:

• Gold is a Lyophobic Colloid.

• In this type of colloidal solutions, the dispersed phase particles have no affinity ("phobic"-"no love") for the dispersed medium.

• These type of sols are irreversible.

• Majority of the colloidal sols of metals lile Silver , Gold , etc are Lyophobic in nature.

Other options are eliminated because:

• Gelatin, starch and haemoglobin are lyophilic sols.

• Here the dispersed phase particles have great affinity ("philic" - "love") towards the dispersion medium.
