Answer 1

Explanation:

Distilled water is usually passed through the ion exchange columns to get de-ionized water. You may check the difference in the pH of both distilled water and de-ionized water and note that pH has a significant effect on the size, shape and stability of electrostatically stabilized particles as is in your's case. I think that particles in your later preparation are less stable and have gone a kind of aggregation. Red color of silver nanoparticles is due to the linear aggregation of less stable silver nanoparticles to form chain-like structures. It is also possible that you hay have particles of several different sizes and Shapes
