Which outcome occurs when excess chloride ions surround silver nanoparticles?

A)Colloidal destabilization via charge screening
B)Increased plasmon resonance bandwidth
C)Enhanced catalytic oxidation activity
D)Suppressed silver ion dissolution

💡 Explanation

Colloidal destabilization occurs because *double layer compression* allows van der Waals forces between nanoparticles to dominate, leading to aggregation. Therefore, destabilization is favored, rather than catalytic enhancement or dissolution suppression which require different surface interactions under different conditions.
