Question

100 mL of 5% (w/v) solution of NaCl in water was prepared in 250 mL beaker. Albumin from the egg was poured into NaCl solution and stirred well. This resulted in a/an :

• A. Lyophilic sol
• B. Lyophobic sol
• C. Emulsion
• D. Precipitate

Answer 1

Answer: (A)

Lyophilic sol

Answer 2

Egg albumin was added to a 100 mL aqueous solution containing 5% (w/v) NaCl. This led to the creation of a lyophilic sol, where albumin molecules dispersed in water and the colloidal particles of albumin were stabilized through hydrogen bonds with water molecules.
So, the correct option is (A): Lyophilic sol.
