Brownian motion of colloidal particles is caused by:

1.	Temperature fluctuations within the liquid phase.
2.	Attraction and repulsion between charges on the colloidal particles.
3.	Impact of the molecules of the dispersion medium on the colloidal particles.
4.	None of the above.

Measuring Zeta potential is useful in determining which of the following property of a colloidal solution:

1. Solubility.

2. Stability of the colloidal particles.

3. Size of the colloidal particles.

4. Viscosity.
