The most appropriate method of making egg albumin sol is:
1 Keep the egg in boiling water for 10 minutes. After removing the shell, transfer the yellow part of the content to \(100 \mathrm{~mL}\) of \(5 \% \mathrm{w} / \mathrm{V}\) saline solution and homogenise with a mechanical shaker.
2 Break an egg carefully and transfer the transparent part of the content to \(100 \mathrm{~mL}\) of \(5 \% \mathrm{w} / \mathrm{V}\) saline solution and stir well.
3 Keep the egg in boiling water for 10 minutes. After removing the shell, transfer the white part of the content to \(100 \mathrm{~mL}\) of \(5 \% \mathrm{w} / \mathrm{V}\) saline solution and homogenise with a mechanical shaker.
4 Break an egg carefully and transfer only the yellow part of the content to \(100 \mathrm{~mL}\) of \(5 \% \mathrm{w} / \mathrm{V}\) saline solution and stir well.
Explanation:
Only the transparent part of egg has albumin.

Bredig's arc method can not be used to prepare colloidal solution of which of the following?
1 \(\mathrm{Pt}\)
2 \(\mathrm{Fe}\)
3 \(\mathrm{Ag}\)
4 \(\mathrm{Au}\)
Explanation:
Bredig's arc method is suitable for the preparation of colloidal solution of metal like gold, silver, platinum etc. An arc is struck between the metal electrode under the surface of water containing some stabilizing agent such as a trace of \(\mathrm{KOH}\). However, Fe does not react with alkalies that is why it is not obtained by Bredig's arc method.
