From: harika Demonstration of the Surface-Effect on Chemical Pr
The colloid is made of nanoscale Ag particles suspended in the aqueous solution. The particles acquire negative charge and remain suspended in solution due to the repulsion caused by the surface adsorption of the citrate anions. Concentrations of AgNO3 and reducing agent, reaction time, solution temperature, etc. influence the particle size.
