The equation 4HNO3 + Zn(OH)2 -> 2NO2 + 2H2O + Zn(NO3)2.

  1. Detailed information about the equation 4HNO3 + Zn(OH)2 -> 2NO2 + 2H2O + Zn(NO3)2

    • 4HNO3 (nitric acid) and Zn(OH)2 (zinc hydroxide) react with each other to produce 2NO2 (nitrogen dioxide), 2H2O (water), and Zn(NO3)2 (zinc nitrate).

  2. Reaction conditions

    • The reaction conditions are at room temperature and standard pressure.

  3. Reaction process

    • The reaction process takes place when nitric acid reacts with zinc hydroxide, producing nitrogen dioxide, water, and zinc nitrate.
    • During this process, zinc hydroxide is oxidized to zinc nitrate, while nitric acid is reduced to nitrogen dioxide.

  4. Phenomena occurring

    • When the reaction occurs, the main product is zinc nitrate, a white solid that is soluble in water, and nitrogen dioxide, a brown gas.
    • If the reaction is carried out in a sealed container, you will see the brown color of nitrogen dioxide appear.
    • If the reaction is carried out in the open air, nitrogen dioxide will escape from the system in the form of gas and water will dissolve zinc nitrate.
    • This reaction also releases heat, so the temperature of the system will increase.
