This extract was then combined with silver nitrate (AgNO3) to initiate a reduction reaction, resulting in the formation of silver nanoparticles. The process was visually confirmed by a color ...

The aldehydes in reducing sugars will reduce silver ion from Tollen's reagent to metallic silver, leaving a reflective mirror on the inside of a flask. To conduct demonstration: 1. Add 5mL 10% AgNO3 ...

Add 0.1M AgNO3 solution dropwise to beaker #5. The color should become less intense as AgSCN is precipitated. Silver solutions will stain skin black on contact; gloves should be worn. Materials may be ...
