The Brownian motion is due to
Temperature fluctuation within the liquid phase
Attraction and repulsion between the charges of the colloidal particles
Impact of molecules of the dispersion medium on the colloidal particles
connective currents
As we learned
Brownian Movement
When colloidal solutions are viewed under a powerful ultramicroscope, the colloidal particles appear to be in a state of continuous zig zag motion all over the field of view. This is known as brownian movement.
The Brownian movement has been explained to be due to the unbalanced bombardment of the particles by the molecules of the dispersion medium.
Hence, the correct answer is Option (3)
5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K

A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A. The leftover organic phase was extracted with d
