FeS dissolved in dilute nitric acid Dissolution of ferrous sulfide in dilute nitric acid
Reaction formula of ferrous sulfide and excessive nitric acid:
FeS+6HNO3=Fe (NO3)3+H2SO4+2H2O+3NO↑
2 Valence ferrous iron lost one electron and increased 1 valence to 3 valence iron and negative 2 valence sulfur lost 8 electrons and increased 8 valence to 6 valence sulfur.
The electron gain and loss in redox reaction are conserved.
