This equation describes the reaction process between Nitric acid (HNO3) and Copper sulfide (Cu2S) to produce Copper(II) nitrate (Cu(NO3)2), water (H2O), Nitric oxide (NO), and Sulfur dioxide (SO2).
- Reaction conditions
The reaction usually takes place in an acidic environment, with appropriate temperature and pressure to generate sufficient energy to stimulate the chemical reaction process.
- Reaction process
In the reaction process, 6 moles of nitric acid react with 2 moles of Copper sulfide to produce 2 moles of Copper(II) nitrate, 3 moles of water, 4 moles of Nitric oxide, and 2 moles of Sulfur dioxide. This chemical reaction process is a type of redox reaction because both HNO3 and Cu2S are oxidized and reduced in the reaction process.
- Observed phenomena
When nitric acid reacts with copper sulfide, changes in color and heat generation can be observed. The product of the reaction, Copper(II) nitrate, forms a blue solid. In addition, Nitric oxide gas and Sulfur dioxide are released into the environment.
