Multiple-choice question: The Zeta potential of colloidal particles refers to: ( ) A. The potential difference between the solid surface and the bulk solution B. The potential difference between the boundary of the tight layer and the diffusion layer and the bulk solution C. The potential difference between the diffusion layer and the bulk solution D. The potential difference between the interface where solid and liquid can move relative to each other and the bulk solution. Answer: D The Zeta potential, also known as electrokinetic potential, becomes apparent only when the colloidal particles are in motion; it represents the potential difference between the interface where solid and liquid can slide past each other and the bulk solution. Hint: The answer can be seen upon reply
D. Potential drop between the solid-liquid interface where relative movement is possible and the bulk solution
D. Potential drop between the solid-liquid interface where relative movement is possible and the bulk solution
D. Potential drop between the solid-liquid interface where relative movement is possible and the bulk solution
D. Potential drop between the solid-liquid interface where relative movement is possible and the bulk solution
