Abstract
Synthesis of silver nanoparticles using ascorbic acid reductant has been carried out. The purpose of this study
was to determine the synthesis process of silver nanoparticles and to determine the stability of silver
nanoparticles based on variations in AgNO3 concentration using ascorbic acid as a reducing agent. In this
synthesis, it was carried out using various concentrations of AgNO3 and ascorbic acid reducing agents. The
characterization used in this research is UV-Vis Spectrophotometer. The results of the UV-Vis
spectrophotometer showed that the concentration of AgNO3 4×10-4 M with ascorbic acid 1×10-3 M was more
stable than other AgNO3 concentrations
