Detailed information about the equation 8HNO3 + 2FeS -> 2Fe(NO3)3 + 2H2O + 8NO + 2SO2:
The above equation describes the reaction between nitric acid (HNO3) and iron sulfide (FeS). The products of the reaction are iron(III) nitrate, water, nitrogen monoxide and sulfur dioxide. -
Reaction conditions:
The reaction is usually carried out at room temperature. However, the temperature can be increased to speed up the reaction. -
Reaction process:
Iron sulfide (FeS) reacts with nitric acid (HNO3) to produce iron(III) nitrate (Fe(NO3)3), water (H2O), nitrogen monoxide (NO) and sulfur dioxide (SO2). -
Phenomena occurring:
During the reaction, brown gas (NO) and pale yellow gas (SO2) are released. This is a redox reaction, where FeS is oxidized to Fe(NO3)3 and HNO3 is reduced to NO.
