• Lyopholic sol

• Emulsion

• Precipitate

Answer 1

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 lyophilic sol.

Explanation:

When albumin (a lyophilic colloid) from egg is added to a 5% NaCl solution and stirred, the albumin forms a stable lyophilic sol due to its affinity for water and the solvent medium. Such sols are stable and do not precipitate immediately. Therefore, the resulting mixture is a lyophilic sol, not a precipitate or emulsion.
