When the particle size of dispersed phase in colloidal solution increases :
Correct answer: B. the Brownian motion becomes slow
- A. the Brownian motion become fast
- B. the Brownian motion becomes slow
- C. Brownian motion remains same
- D. none of these
Explanation
Brownian movement is due to the unequal bombardments of the moving molecules of dispersion medium on colloidal particles. Bigger size of particle reduces the momentum.
