The equation 4HNO3 + Ag -> AgNO3 + 2H2O + 2NO2

  1. Detailed information about the chemical equation 4HNO3 + Ag -> AgNO3 + 2H2O + 2NO2

    • This is a chemical equation describing the reaction process between nitric acid (HNO3) and silver (Ag) to form silver nitrate (AgNO3), water (H2O) and nitrogen dioxide (NO2).
    • In the equation, the number of atoms of each element on both sides of the reaction is equal, adhering to the law of conservation of atoms.

  2. Reaction conditions

    • The reaction occurs when nitric acid (HNO3) comes into contact with silver (Ag) under normal temperature and pressure conditions.
    • Highly concentrated nitric acid is required for the reaction to take place.

  3. Reaction process

    • When nitric acid and silver come into contact, nitric acid oxidizes silver into silver nitrate.
    • In this process, nitric acid is also reduced to nitrogen dioxide and water.

  4. Phenomena occur

    • When the reaction occurs, silver gradually disappears and the color of the solution gradually changes to reddish-brown due to the presence of nitrogen dioxide.
    • Brown gas bubbles (nitrogen dioxide) can be seen rising.
    • If the reaction takes place in a solution, the solution after the reaction will turn white due to the formation of silver nitrate.
