- Which of the following is a correct statement? Option: 1 Brownian motion destabilises sols.<div class='qna-option
Which of the following is a correct statement?
Brownian motion destabilises sols.
Any amount of dispered phase can be added to emulsion without destabilising it.
Mixing two oppositely charged sols in equal amount neutralises charges and stabilises colloids.
Presence of equal and similar charges and colloidal particles provides stability to the colloidal solution.
Answers (1)
As we have learnt
- Browian motion stabilizes colloidal solutions.
- Any amout of dispersion medium can be added to an emulsion without destabilising it.
- Mixing of two oppositely charged sols causes precipitation of sols.
- Presence of equal and similar charges on colloidal particle causes repulsion among them and does not let them settle or coagulate, thus providing stability to the colloidal solution
Hence correct option is 4
