Which of the following is a correct statement?
1
Brownian motion destabilises sols.
2
Any amount of dispersed phase can be added to emulsion without destabilising it.
3
Mixing two oppositely charged sols in equal amount neutralises charges and stabilises colloids.
4
Presence of equal and similar charges on colloidal particles provides stability to the colloidal solution.

Using very little soap while washing clothes, does not serve the purpose of cleaning of clothes, because:
1
soap particles remain floating in water as ions.
2
the hydrophobic part of soap is not able to take away grease.
3
the micelles are not formed due to concentration of soap, below its CMC value.
4
colloidal structure of soap in water is completely distributed.
