Question

Write a chemical equation for the reduction step in hte formation of silver nanoparticles

Answer 1

For the formation of any metal nano-particles, a reduction reaction takes place. In this reaction, the metal ion reacts with a reducing agent to form a metal nano-particle.
Similarly, for the formation silver nano-particles, the silver ions must get reduced to elemental silver.
