Diluted nitric acid oxidizes hydrogen sulfide to sulfur on the fly, and itself is reduced to nitric oxide (2) make up the equation of the reaction.
The equation for the reaction of hydrogen sulfide and dilute nitric acid:
3H2S + 2HNO3 => 2NO + 3S + 4H2O.
Nitric acid, even when diluted, is a strong oxidizing agent. In this reaction, nitrogen is reduced from the oxidation state (+5) to (+2), and sulfur is oxidized from (-2) to (0).
