The chemical equation 6HNO3 + 2Mn -> 4NO2 + 2H2O + 2Mn(NO3)2.

  1. Detailed information about the equation 6HNO3 + 2Mn -> 4NO2 + 2H2O + 2Mn(NO3)2:
    This equation describes the reaction between Nitric acid (HNO3) and Manganese (Mn). The products of this reaction are Nitrogen dioxide (NO2), Water (H2O), and Manganese(II) nitrate (Mn(NO3)2).

  2. Reaction conditions:
    The reaction usually takes place at room temperature and atmospheric pressure. However, the reaction rate might increase if the temperature is raised.

  3. Reaction process:
    When Nitric acid reacts with Manganese, Nitrogen dioxide, Water, and Manganese(II) nitrate are formed. This process is a type of redox reaction, where Manganese is oxidized from an oxidation state of +2 to +7, while Nitrogen in HNO3 is reduced from an oxidation state of +5 to +4.

  4. Phenomena that occur:
    During the reaction, the initial mixture may remain unchanged in color or some gas bubbles (Nitrogen dioxide) may be seen escaping. Simultaneously, the solution will have a pale pink color due to the presence of Manganese(II) nitrate.
