Question

Zeta potential is

• A. Potential required to bring about coagulation of a colloidal sol.
• B. Potential required to give the particle a speed of 1 cm S^-1
• C. Potential difference between fixed charged layer and the diffused layer having opposite charges
• D. Potential energy of the colloidal particles.

Answer 1

The Correct Option is C

Zeta potential is the potential difference between the fixed charged layer and the diffused layer surrounding a colloidal particle. It plays a key role in the stability of colloidal suspensions, as it influences the extent of repulsion between particles, preventing coagulation or flocculation.

The correct answer is (C) : Potential difference between fixed charged layer and the diffused layer having opposite charges.
