Detailed information about the equation 6HNO3 + 2FeS -> 4NO2 + 2H2O + 2Fe(NO3)3 + 2S:
The above chemical equation describes the reaction between nitric acid (HNO3) and pyrite (FeS). The result of this reaction is a product that includes nitrogen dioxide (NO2), water (H2O), iron(III) nitrate (Fe(NO3)3), and sulfur (S). -
Reaction conditions:
For the reaction to occur, the presence of a strong acid (in this case, nitric acid) is required. Simultaneously, temperature and pressure also need to be controlled at a certain level. -
Reaction process:
-
Phenomena occurring:
During the reaction process, changes in color and gas production can be observed. The color of the solution may turn brown due to the appearance of nitrogen dioxide gas. At the same time, sulfur is released in the form of yellow gas.
