The equation ZnS + HNO3 -> Zn(NO3)2 + H2S

  1. Detailed information about the equation ZnS + HNO3 -> Zn(NO3)2 + H2S:

The chemical equation above describes the reaction process between zinc sulfide (ZnS) and nitric acid (HNO3) to form zinc nitrate (Zn(NO3)2) and hydrogen sulfide (H2S).

  1. Reaction conditions:

The reaction occurs when ZnS is dissolved in excess HNO3 solution and at an appropriate temperature.

  1. Reaction process:

When zinc sulfide (ZnS) is dissolved in nitric acid (HNO3), it forms zinc nitrate (Zn(NO3)2) and hydrogen sulfide (H2S). Hydrogen sulfide is a yellow gas with a very characteristic foul smell.

  1. Phenomena that occur:

During the reaction, the white solid of zinc sulfide (ZnS) will gradually disappear, replaced by the appearance of a white solution of zinc nitrate (Zn(NO3)2) and the escape of foul-smelling hydrogen sulfide gas.
