Measuring Zeta potential is useful in determining which property of colloidal solution?

1. Solubility
2. Stability of the colloidal particles
3. Size of the colloidal particles
4. Viscosity

Correct answer: Stability of the colloidal particles

Solution

Zeta potential is a measure of the electric potential at the slipping plane of colloidal particles, which directly influences their stability by preventing aggregation due to electrostatic repulsion.
