Equation K2S + HNO3 -> 2KNO3 + H2S

  1. Detailed information about the equation K2S + HNO3 -> 2KNO3 + H2S:

    • On the left side of the equation, K2S is Potassium sulfide and HNO3 is Nitric acid.
    • On the right side of the equation, 2KNO3 is Potassium nitrate and H2S is Hydrogen sulfide.
    • The equation indicates that when Potassium sulfide reacts with Nitric acid, it will form Potassium nitrate and Hydrogen sulfide.

  2. Reaction conditions: Potassium sulfide and Nitric acid must exist in standard temperature and pressure conditions.

  3. Reaction process: When the substances K2S and HNO3 are mixed together, a chemical reaction will occur, forming 2KNO3 and H2S. During this process, the K+ ions from K2S will bond with the NO3- ions from HNO3 to form KNO3. The H+ ions from HNO3 will bond with the S2- ions from K2S to form H2S.

  4. Phenomena occurring: During the reaction, there will be a bubbling effect due to the escape of H2S. The smell of H2S can also be perceived as H2S has a distinctive foul odor.
