The above chemical equation represents the redox reaction between nitric acid (HNO3) and silver (Ag). In the reaction, silver is oxidized to AgNO3, while nitric acid is reduced to NO2.
- Reaction conditions
This reaction occurs when concentrated nitric acid reacts with silver.
- Reaction process
When concentrated nitric acid reacts with silver, silver is oxidized to Ag+ ion (forming AgNO3) and nitric acid after being reduced will form NO2. In this process, water is also produced.
- Phenomena occurring
The main phenomena that can be seen in this reaction are the red color of the NO2 gas being released and the appearance of the white crystals of AgNO3. As the reaction progresses, the silver powder gradually disappears and a thin white layer of AgNO3 forms on the surface.
