Answer:
Explanation:
" the ceaseless, erratic, zig-zag motion exhibited by colloidal particles is called Brownian motion"
- it is due to unequal bombardment of colloidal particle by constantly moving molecules dispersion medium.
- Brownian motion of of sol particles is slower than the molecular motion because colloidal particles are heavier than molecules
- since brownian motion counteracts the force of gravity acting on the colloidal particles, it is responsible to some extent for the stability of colloidal solutions
